altair.Chart

class altair.Chart(data=Undefined, encoding=Undefined, mark=Undefined, width=Undefined, height=Undefined, **kwargs)

Create a basic Altair/Vega-Lite chart.

Although it is possible to set all Chart properties as constructor attributes, it is more idiomatic to use methods such as mark_point(), encode(), transform_filter(), properties(), etc. See Altair’s documentation for details and examples: http://altair-viz.github.io/.

Attributes

dataData

An object describing the data source

markAnyMark

orientOrientation

The orientation of a non-stacked bar, tick, area, and line charts. The value is either horizontal (default) or vertical.

• For bar, rule and tick, this determines whether the size of the bar and tick

should be applied to x or y dimension. * For area, this property determines the orient property of the Vega output. * For line and trail marks, this property determines the sort order of the points in

the line

if config.sortLineBy is not specified. For stacked charts, this is always determined by the orientation of the stack; therefore explicitly specified value will be ignored.

pointanyOf(boolean, OverlayMarkDef, enum(‘transparent’))

A flag for overlaying points on top of line or area marks, or an object defining the properties of the overlayed points.

If this property is "transparent", transparent points will be used (for enhancing tooltips and selections).

If this property is an empty object ( {} ) or true, filled points with default properties will be used.

If this property is false, no points would be automatically added to line or area marks.

Default value: false.

• For text, this represents the font size, in pixels.

Default value:

• 30 for point, circle, square marks; width/height’s step

• 2 for bar marks with discrete dimensions;

• 5 for bar marks with continuous dimensions;

• 11 for text marks.

domainOpacityfloat

Opacity of the axis domain line.

domainWidthfloat

Stroke width of axis domain line

Default value: 1

gridboolean

A boolean flag indicating if grid lines should be included as part of the axis

Default value: true for continuous scales that are not binned; otherwise, false.

Default value: -90 for nominal and ordinal fields; 0 otherwise.

labelBaselineanyOf(TextBaseline, ConditionalAxisLabelBaseline)

labelBoundanyOf(float, boolean)

Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.

Default value: false.

labelColoranyOf(anyOf(None, Color), ConditionalAxisColor)

labelExprstring

Vega expression for customizing labels.

Note: The label text and value can be assessed via the label and value properties of the axis’s backing datum object.

labelFlushanyOf(boolean, float)

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffsetfloat

Indicates the number of pixels by which to offset flush-adjusted labels. For example, a value of 2 will push flush-adjusted labels 2 pixels outward from the center of the axis. Offsets can help the labels better visually group with corresponding axis ticks.

If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

labelPaddinganyOf(float, ConditionalAxisNumber)

Default value: "bottom" for x-axes and "left" for y-axes.

styleanyOf(string, List(string))

A string or array of strings indicating the name of custom styles to apply to the axis. A style is a named collection of axis property defined within the style configuration. If style is an array, later styles will override earlier styles.

Default value: (none) Note: Any specified style will augment the default style. For example, an x-axis mark with "style": "foo" will use config.axisX and config.style.foo (the specified style "foo" has higher precedence).

tickBandenum(‘center’, ‘extent’)

For band scales, indicates if ticks and grid lines should be placed at the center of a band (default) or at the band extents to indicate intervals.

tickColoranyOf(anyOf(None, Color), ConditionalAxisColor)

tickCountfloat

A desired number of ticks, for axes visualizing quantitative scales. The resulting number may be different so that values are “nice” (multiples of 2, 5, 10) and lie within the underlying scale’s range.

Default value : Determine using a formula ceil(width/40) for x and ceil(height/40) for y.

tickDashanyOf(List(float), ConditionalAxisNumberArray)

Attributes

bandPositionfloat

An interpolation fraction indicating where, for band scales, axis ticks should be positioned. A value of 0 places ticks at the left edge of their bands. A value of 0.5 places ticks in the middle of their bands.

Default value: 0.5

disableboolean

Disable axis by default.

domainboolean

A boolean flag indicating if the domain (the axis baseline) should be included as part of the axis.

Default value: true

domainColoranyOf(None, Color)

Color of axis domain line.

Default value: "gray".

domainDashList(float)

An array of alternating [stroke, space] lengths for dashed domain lines.

domainDashOffsetfloat

The pixel offset at which to start drawing with the domain dash array.

domainOpacityfloat

Opacity of the axis domain line.

domainWidthfloat

Stroke width of axis domain line

Default value: 1

gridboolean

A boolean flag indicating if grid lines should be included as part of the axis

Default value: true for continuous scales that are not binned; otherwise, false.

gridOpacityanyOf(float, ConditionalAxisNumber)

gridWidthanyOf(float, ConditionalAxisNumber)

labelAlignanyOf(Align, ConditionalAxisLabelAlign)

labelAnglefloat

The rotation angle of the axis labels.

Default value: -90 for nominal and ordinal fields; 0 otherwise.

labelBaselineanyOf(TextBaseline, ConditionalAxisLabelBaseline)

labelBoundanyOf(float, boolean)

Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.

Default value: false.

labelColoranyOf(anyOf(None, Color), ConditionalAxisColor)

labelExprstring

Vega expression for customizing labels.

Note: The label text and value can be assessed via the label and value properties of the axis’s backing datum object.

labelFlushanyOf(boolean, float)

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffsetfloat

Indicates the number of pixels by which to offset flush-adjusted labels. For example, a value of 2 will push flush-adjusted labels 2 pixels outward from the center of the axis. Offsets can help the labels better visually group with corresponding axis ticks.

Default value: 0.

labelFontanyOf(string, ConditionalAxisString)

labelFontSizeanyOf(float, ConditionalAxisNumber)

labelOpacityanyOf(float, ConditionalAxisNumber)

labelOverlapLabelOverlap

The strategy to use for resolving overlap of axis labels. If false (the default), no overlap reduction is attempted. If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

labelPaddinganyOf(float, ConditionalAxisNumber)

labelSeparationfloat

The minimum separation that must be between label bounding boxes for them to be considered non-overlapping (default 0 ). This property is ignored if labelOverlap resolution is not enabled.

labelsboolean

Default value: true.

maxExtentfloat

The maximum extent in pixels that axis ticks and labels should use. This determines a maximum offset value for axis titles.

Default value: undefined.

minExtentfloat

The minimum extent in pixels that axis ticks and labels should use. This determines a minimum offset value for axis titles.

Default value: 30 for y-axis; undefined for x-axis.

offsetfloat

The offset, in pixels, by which to displace the axis from the edge of the enclosing group or data rectangle.

Default value: derived from the axis config ‘s offset ( 0 by default)

orientAxisOrient

The orientation of the axis. One of "top", "bottom", "left" or "right". The orientation can be used to further specialize the axis type (e.g., a y-axis oriented towards the right edge of the chart).

Default value: "bottom" for x-axes and "left" for y-axes.

styleanyOf(string, List(string))

A string or array of strings indicating the name of custom styles to apply to the axis. A style is a named collection of axis property defined within the style configuration. If style is an array, later styles will override earlier styles.

Default value: (none) Note: Any specified style will augment the default style. For example, an x-axis mark with "style": "foo" will use config.axisX and config.style.foo (the specified style "foo" has higher precedence).

tickBandenum(‘center’, ‘extent’)

For band scales, indicates if ticks and grid lines should be placed at the center of a band (default) or at the band extents to indicate intervals.

tickColoranyOf(anyOf(None, Color), ConditionalAxisColor)

tickCountfloat

A desired number of ticks, for axes visualizing quantitative scales. The resulting number may be different so that values are “nice” (multiples of 2, 5, 10) and lie within the underlying scale’s range.

Default value : Determine using a formula ceil(width/40) for x and ceil(height/40) for y.

tickDashanyOf(List(float), ConditionalAxisNumberArray)

tickDashOffsetanyOf(float, ConditionalAxisNumber)

tickExtraboolean

Default value: false.

labelColoranyOf(anyOf(None, Color), ConditionalAxisColor)

labelExprstring

Vega expression for customizing labels.

Note: The label text and value can be assessed via the label and value properties of the axis’s backing datum object.

labelFlushanyOf(boolean, float)

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffsetfloat

Indicates the number of pixels by which to offset flush-adjusted labels. For example, a value of 2 will push flush-adjusted labels 2 pixels outward from the center of the axis. Offsets can help the labels better visually group with corresponding axis ticks.

If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

labelPaddinganyOf(float, ConditionalAxisNumber)

labelSeparationfloat

Default value: derived from the axis config ‘s offset ( 0 by default)

orientAxisOrient

The orientation of the axis. One of "top", "bottom", "left" or "right". The orientation can be used to further specialize the axis type (e.g., a y-axis oriented towards the right edge of the chart).

Default value: "bottom" for x-axes and "left" for y-axes.

styleanyOf(string, List(string))

A string or array of strings indicating the name of custom styles to apply to the axis. A style is a named collection of axis property defined within the style configuration. If style is an array, later styles will override earlier styles.

Default value: (none) Note: Any specified style will augment the default style. For example, an x-axis mark with "style": "foo" will use config.axisX and config.style.foo (the specified style "foo" has higher precedence).

tickBandenum(‘center’, ‘extent’)

For band scales, indicates if ticks and grid lines should be placed at the center of a band (default) or at the band extents to indicate intervals.

tickColoranyOf(anyOf(None, Color), ConditionalAxisColor)

tickCountfloat

A desired number of ticks, for axes visualizing quantitative scales. The resulting number may be different so that values are “nice” (multiples of 2, 5, 10) and lie within the underlying scale’s range.

Default value : Determine using a formula ceil(width/40) for x and ceil(height/40) for y.

tickDashanyOf(List(float), ConditionalAxisNumberArray)

tickDashOffsetanyOf(float, ConditionalAxisNumber)

If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffsetfloat

If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

Default value: "bottom" for x-axes and "left" for y-axes.

styleanyOf(string, List(string))

A string or array of strings indicating the name of custom styles to apply to the axis. A style is a named collection of axis property defined within the style configuration. If style is an array, later styles will override earlier styles.

Default value: (none) Note: Any specified style will augment the default style. For example, an x-axis mark with "style": "foo" will use config.axisX and config.style.foo (the specified style "foo" has higher precedence).

tickBandenum(‘center’, ‘extent’)

For band scales, indicates if ticks and grid lines should be placed at the center of a band (default) or at the band extents to indicate intervals.

tickColoranyOf(anyOf(None, Color), ConditionalAxisColor)

Color of axis domain line.

Default value: "gray".

domainDashList(float)

An array of alternating [stroke, space] lengths for dashed domain lines.

domainDashOffsetfloat

The pixel offset at which to start drawing with the domain dash array.

domainOpacityfloat

Opacity of the axis domain line.

domainWidthfloat

Stroke width of axis domain line

Default value: 1

Default value: -90 for nominal and ordinal fields; 0 otherwise.

labelBaselineanyOf(TextBaseline, ConditionalAxisLabelBaseline)

labelBoundanyOf(float, boolean)

Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.

Default value: false.

labelColoranyOf(anyOf(None, Color), ConditionalAxisColor)

labelExprstring

Vega expression for customizing labels.

Note: The label text and value can be assessed via the label and value properties of the axis’s backing datum object.

labelFlushanyOf(boolean, float)

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffsetfloat

Indicates the number of pixels by which to offset flush-adjusted labels. For example, a value of 2 will push flush-adjusted labels 2 pixels outward from the center of the axis. Offsets can help the labels better visually group with corresponding axis ticks.

Default value: "bottom" for x-axes and "left" for y-axes.

styleanyOf(string, List(string))

A string or array of strings indicating the name of custom styles to apply to the axis. A style is a named collection of axis property defined within the style configuration. If style is an array, later styles will override earlier styles.

Default value: (none) Note: Any specified style will augment the default style. For example, an x-axis mark with "style": "foo" will use config.axisX and config.style.foo (the specified style "foo" has higher precedence).

tickBandenum(‘center’, ‘extent’)

For band scales, indicates if ticks and grid lines should be placed at the center of a band (default) or at the band extents to indicate intervals.

An array of alternating [stroke, space] lengths for dashed domain lines.

domainDashOffsetfloat

The pixel offset at which to start drawing with the domain dash array.

domainOpacityfloat

Opacity of the axis domain line.

domainWidthfloat

Stroke width of axis domain line

Default value: 1

gridboolean

A boolean flag indicating if grid lines should be included as part of the axis

Default value: true for continuous scales that are not binned; otherwise, false.

Default value: -90 for nominal and ordinal fields; 0 otherwise.

labelBaselineanyOf(TextBaseline, ConditionalAxisLabelBaseline)

labelBoundanyOf(float, boolean)

Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.

Default value: false.

labelColoranyOf(anyOf(None, Color), ConditionalAxisColor)

labelExprstring

Vega expression for customizing labels.

Note: The label text and value can be assessed via the label and value properties of the axis’s backing datum object.

labelFlushanyOf(boolean, float)

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffsetfloat

Indicates the number of pixels by which to offset flush-adjusted labels. For example, a value of 2 will push flush-adjusted labels 2 pixels outward from the center of the axis. Offsets can help the labels better visually group with corresponding axis ticks.

The strategy to use for resolving overlap of axis labels. If false (the default), no overlap reduction is attempted. If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

labelPaddinganyOf(float, ConditionalAxisNumber)

Default value: derived from the axis config ‘s offset ( 0 by default)

orientAxisOrient

The orientation of the axis. One of "top", "bottom", "left" or "right". The orientation can be used to further specialize the axis type (e.g., a y-axis oriented towards the right edge of the chart).

Default value: "bottom" for x-axes and "left" for y-axes.

styleanyOf(string, List(string))

A string or array of strings indicating the name of custom styles to apply to the axis. A style is a named collection of axis property defined within the style configuration. If style is an array, later styles will override earlier styles.

Default value: (none) Note: Any specified style will augment the default style. For example, an x-axis mark with "style": "foo" will use config.axisX and config.style.foo (the specified style "foo" has higher precedence).

tickBandenum(‘center’, ‘extent’)

For band scales, indicates if ticks and grid lines should be placed at the center of a band (default) or at the band extents to indicate intervals.

tickColoranyOf(anyOf(None, Color), ConditionalAxisColor)

tickCountfloat

A desired number of ticks, for axes visualizing quantitative scales. The resulting number may be different so that values are “nice” (multiples of 2, 5, 10) and lie within the underlying scale’s range.

Default value : Determine using a formula ceil(width/40) for x and ceil(height/40) for y.

tickDashanyOf(List(float), ConditionalAxisNumberArray)

tickDashOffsetanyOf(float, ConditionalAxisNumber)

• For bar, rule and tick, this determines whether the size of the bar and tick

should be applied to x or y dimension. * For area, this property determines the orient property of the Vega output. * For line and trail marks, this property determines the sort order of the points in

the line

if config.sortLineBy is not specified. For stacked charts, this is always determined by the orientation of the stack; therefore explicitly specified value will be ignored.

• a custom SVG path string (For correct sizing, custom shape paths should be defined within a square bounding box with coordinates ranging from -1 to 1 along both the x and y dimensions.)

Default value: "circle"

sizefloat

Default size for marks.

• For point / circle / square, this represents the pixel area of the marks. Note that this value sets the area of the symbol; the side lengths will increase with the square root of this value.

• For bar, this represents the band size of the bar, in pixels.

• For text, this represents the font size, in pixels.

Default value:

• 30 for point, circle, square marks; width/height’s step

Default value: 1

strokeWidthfloat

The stroke width, in pixels.

tensionfloat

Depending on the interpolation type, sets the tension parameter (for line and area marks).

textText

timeUnitBandfloat

Default relative band size for a time unit. If set to 1, the bandwidth of the marks will be equal to the time unit band step. If set to 0.5, bandwidth of the marks will be half of the time unit band step.

timeUnitBandPositionfloat

Default relative band position for a time unit. If set to 0, the marks will be positioned at the beginning of the time unit band step. If set to 0.5, the marks will be positioned in the middle of the time unit band step.

tooltipanyOf(float, string, boolean, TooltipContent, None)

The tooltip text string to show upon mouse hover or an object defining which fields should the tooltip be derived from.

• If tooltip is true or {"content": "encoding"}, then all fields from encoding will be used.

• If tooltip is {"content": "data"}, then all fields that appear in the highlighted data point will be used.

• If set to null or false, then no tooltip will be used.

See the tooltip documentation for a detailed discussion about tooltip in Vega-Lite.

Default value: null

Attributes

typeProjectionType

The cartographic projection to use. This value is case-insensitive, for example “albers” and “Albers” indicate the same projection type. You can find all valid projection types [in the documentation](https://vega.github.io/vega-lite/docs/projection.html#projection-types).

Default value: mercator

centerList(float)

Sets the projection’s center to the specified center, a two-element array of longitude and latitude in degrees.

Default value: [0, 0]

clipAnglefloat

Sets the projection’s clipping circle radius to the specified angle in degrees. If null, switches to [antimeridian](http://bl.ocks.org/mbostock/3788999) cutting rather than small-circle clipping.

clipExtentList(List(float))

Sets the projection’s viewport clip extent to the specified bounds in pixels. The extent bounds are specified as an array [[x0, y0], [x1, y1]], where x0 is the left-side of the viewport, y0 is the top, x1 is the right and y1 is the bottom. If null, no viewport clipping is performed.

coefficientfloat

distancefloat

fractionfloat

lobesfloat

parallelfloat

precisionMapping(required=[length])

Sets the threshold for the projection’s [adaptive resampling](http://bl.ocks.org/mbostock/3795544) to the specified value in pixels. This value corresponds to the [Douglas–Peucker distance](http://en.wikipedia.org/wiki/Ramer%E2%80%93Douglas%E2%80%93Peucker_algorithm).

If precision is not specified, returns the projection’s current resampling

precision which defaults to √0.5 ≅ 0.70710….

radiusfloat

ratiofloat

reflectXboolean

reflectYboolean

rotateList(float)

Sets the projection’s three-axis rotation to the specified angles, which must be a two- or three-element array of numbers [lambda, phi, gamma] specifying the rotation angles in degrees about each spherical axis. (These correspond to yaw, pitch and roll.)

Default value: [0, 0, 0]

Returns

selfChart object

returns chart to allow for chaining

See also

alt.AggregateTransform

underlying transform object

Examples

The aggregate transform allows you to specify transforms directly using the same shorthand syntax as used in encodings:

>>> import altair as alt
>>> chart1 = alt.Chart().transform_aggregate(
...     mean_acc='mean(Acceleration)',
...     groupby=['Origin']
... )
>>> print(chart1.transform[0].to_json())  
{
  "aggregate": [
    {
      "as": "mean_acc",
      "field": "Acceleration",
      "op": "mean"
    }
  ],
  "groupby": [
    "Origin"
  ]
}

It also supports including AggregatedFieldDef instances or dicts directly, so you can create the above transform like this:

>>> chart2 = alt.Chart().transform_aggregate(
...     [alt.AggregatedFieldDef(field='Acceleration', op='mean',
...                             **{'as': 'mean_acc'})],
...     groupby=['Origin']
... )
>>> chart2.transform == chart1.transform
True

transform_bin(self, as_=Undefined, field=Undefined, bin=True, **kwargs)

fieldstring

The data field to bin.

Returns

selfChart object

returns chart to allow for chaining

See also

alt.BinTransform

underlying transform object

Examples

>>> import altair as alt
>>> chart = alt.Chart().transform_bin("x_binned", "x")
>>> chart.transform[0]
BinTransform({
  as: 'x_binned',
  bin: True,
  field: 'x'
})

>>> chart = alt.Chart().transform_bin("x_binned", "x",
...                                   bin=alt.Bin(maxbins=10))
>>> chart.transform[0]
BinTransform({
  as: 'x_binned',
  bin: BinParams({
    maxbins: 10
  }),
  field: 'x'
})

transform_calculate(self, as_=Undefined, calculate=Undefined, **kwargs)

Add a CalculateTransform to the schema.

The field for storing the computed formula value.

calculatestring or alt.expr expression

A expression string. Use the variable datum to refer to the current data object.

**kwargs

transforms can also be passed by keyword argument; see Examples

Returns

selfChart object

See also

alt.CalculateTransform

underlying transform object

Examples

>>> import altair as alt
>>> from altair import datum, expr

>>> chart = alt.Chart().transform_calculate(y = 2 * expr.sin(datum.x))
>>> chart.transform[0]
CalculateTransform({
  as: 'y',
  calculate: (2 * sin(datum.x))
})

It’s also possible to pass the CalculateTransform arguments directly:

>>> kwds = {'as': 'y', 'calculate': '2 * sin(datum.x)'}
>>> chart = alt.Chart().transform_calculate(**kwds)
>>> chart.transform[0]
CalculateTransform({
  as: 'y',
  calculate: '2 * sin(datum.x)'
})

As the first form is easier to write and understand, that is the recommended method.

The data field for which the missing values should be imputed.

keystring

A key field that uniquely identifies data objects within a group. Missing key values (those occurring in the data but not in the current group) will be imputed.

frameList(anyOf(None, float))

A frame specification as a two-element array used to control the window over which the specified method is applied. The array entries should either be a number indicating the offset from the current data object, or null to indicate unbounded rows preceding or following the current data object. For example, the value [-5, 5] indicates that the window should include five objects preceding and five objects following the current object. Default value: : [null, null] indicating that the window includes all objects.

groupbyList(string)

An optional array of fields by which to group the values. Imputation will then be performed on a per-group basis.

keyvalsanyOf(List(Mapping(required=[])), ImputeSequence)

Defines the key values that should be considered for imputation. An array of key values or an object defining a number sequence. If provided, this will be used in addition to the key values observed within the input data. If not provided, the values will be derived from all unique values of the key field. For impute in encoding, the key field is the x-field if the y-field is imputed, or vice versa. If there is no impute grouping, this property must be specified.

methodImputeMethod

The imputation method to use for the field value of imputed data objects. One of value, mean, median, max or min. Default value: "value"

valueMapping(required=[])

The field value to use when the imputation method is "value".

transform_stack(self, as_, stack, groupby, offset=Undefined, sort=Undefined)

Add a StackTransform to the schema.

Parameters

as_anyOf(string, List(string))

transform_timeunit(self, as_=Undefined, field=Undefined, timeUnit=Undefined, **kwargs)

Add a TimeUnitTransform to the schema.

Parameters

as_string

The output field to write the timeUnit value.

fieldstring

The data field to apply time unit.

timeUnitTimeUnit

The timeUnit.

**kwargs

transforms can also be passed by keyword argument; see Examples

Returns

selfChart object

returns chart to allow for chaining

See also

alt.TimeUnitTransform

underlying transform object

Examples

>>> import altair as alt
>>> from altair import datum, expr

>>> chart = alt.Chart().transform_timeunit(month='month(date)')
>>> chart.transform[0]
TimeUnitTransform({
  as: 'month',
  field: 'date',
  timeUnit: 'month'
})

It’s also possible to pass the TimeUnitTransform arguments directly; this is most useful in cases where the desired field name is not a valid python identifier:

>>> kwds = {'as': 'month', 'timeUnit': 'month', 'field': 'The Month'}
>>> chart = alt.Chart().transform_timeunit(**kwds)
>>> chart.transform[0]
TimeUnitTransform({
  as: 'month',
  field: 'The Month',
  timeUnit: 'month'
})

As the first form is easier to write and understand, that is the recommended method.

transform_window(self, window=Undefined, frame=Undefined, groupby=Undefined, ignorePeers=Undefined, sort=Undefined, **kwargs)

Add a WindowTransform to the schema

Parameters

windowList(WindowFieldDef)

The definition of the fields in the window, and what calculations to use.

frameList(anyOf(None, float))

A frame specification as a two-element array indicating how the sliding window should proceed. The array entries should either be a number indicating the offset from the current data object, or null to indicate unbounded rows preceding or following the current data object. The default value is [null, 0], indicating that the sliding window includes the current object and all preceding objects. The value [-5, 5] indicates that the window should include five objects preceding and five objects following the current object. Finally, [null, null] indicates that the window frame should always include all data objects. The only operators affected are the aggregation operations and the first_value, last_value, and nth_value window operations. The other window operations are not affected by this.

Default value: : [null, 0] (includes the current object and all preceding objects)

groupbyList(string)

The data fields for partitioning the data objects into separate windows. If unspecified, all data points will be in a single group.

ignorePeersboolean

Indicates if the sliding window frame should ignore peer values. (Peer values are those considered identical by the sort criteria). The default is false, causing the window frame to expand to include all peer values. If set to true, the window frame will be defined by offset values only. This setting only affects those operations that depend on the window frame, namely aggregation operations and the first_value, last_value, and nth_value window operations.

Default value: false

sortList(SortField)

A sort field definition for sorting data objects within a window. If two data objects are considered equal by the comparator, they are considered “peer” values of equal rank. If sort is not specified, the order is undefined: data objects are processed in the order they are observed and none are considered peers (the ignorePeers parameter is ignored and treated as if set to true ).

**kwargs

transforms can also be passed by keyword argument; see Examples

Examples

A cumulative line chart

>>> import altair as alt
>>> import numpy as np
>>> import pandas as pd
>>> data = pd.DataFrame({'x': np.arange(100),
...                      'y': np.random.randn(100)})
>>> chart = alt.Chart(data).mark_line().encode(
...     x='x:Q',
...     y='ycuml:Q'
... ).transform_window(
...     ycuml='sum(y)'
... )
