The ratio of the graph scaling between the longest axis on the horizontal plane and the y-axis. Defaults to 2.0.

Note: Has no effect on Bars3D.

This property was introduced in QtDataVisualization 1.1.

See also horizontalAspectRatio.

When FPS measuring is enabled, the results for the last second are stored in this read-only property. It takes at least a second before this value updates after measuring is activated.

This property was introduced in QtDataVisualization 1.1.

See also measureFps.

The list of Custom3DItem items added to the graph. The graph takes ownership of the added items.

This property was introduced in QtDataVisualization 1.1.

The ratio of the graph scaling between the x-axis and z-axis. The value of 0.0 indicates automatic scaling according to axis ranges. Defaults to 0.0.

Note: Has no effect on Bars3D, which handles scaling on the horizontal plane via the barThickness and barSpacing properties. Polar graphs also ignore this property.

This property was introduced in QtDataVisualization 1.2.

See also aspectRatio, polar, Bars3D::barThickness, and Bars3D::barSpacing.

The active input handler used in the graph. You can disable default input handlers by setting this property to null.

Sets the locale used for formatting various numeric labels. Defaults to the "C" locale.

This property was introduced in QtDataVisualization 1.2.

See also ValueAxis3D::labelFormat.

The absolute value used for the space left between the edge of the plottable graph area and the edge of the graph background.

If the margin value is negative, the margins are determined automatically and can vary according to the size of the items in the series and the type of the graph. The value is interpreted as a fraction of the y-axis range if the graph aspect ratios have not beed changed from the default values. Defaults to -1.0.

Note: Setting a smaller margin for a scatter graph than the automatically determined margin can cause the scatter items at the edges of the graph to overlap with the graph background.

Note: On scatter and surface graphs, if the margin is small in comparison to the axis label size, the positions of the edge labels of the axes are adjusted to avoid overlap with the edge labels of the neighboring axes.

This property was introduced in QtDataVisualization 1.2.

If true, the rendering is done continuously instead of on demand, and the value of the currentFps property is updated. Defaults to false.

This property was introduced in QtDataVisualization 1.1.

See also currentFps.

The number of samples used in multisample antialiasing when renderingMode is RenderIndirect. When renderingMode is RenderDirectToBackground or RenderDirectToBackground_NoClear, this property value is read-only and returns the number of samples specified by the window surface format. Defaults to 4.

See also renderingMode.

Whether the default or static mode is used for rendering optimization.

The default mode provides the full feature set at a reasonable level of performance. The static mode optimizes graph rendering and is ideal for large non-changing data sets. It is slower with dynamic data changes and item rotations. Selection is not optimized, so using the static mode with massive data sets is not advisable. Static optimization works only on scatter graphs. Defaults to OptimizationDefault.

Note: On some environments, large graphs using static optimization may not render, because all of the items are rendered using a single draw call, and different graphics drivers support different maximum vertice counts per call. This is mostly an issue on 32bit and OpenGL ES2 platforms. To work around this issue, choose an item mesh with a low vertex count or use the point mesh.

This property was introduced in QtDataVisualization 1.1.

See also Abstract3DSeries::mesh and QAbstract3DGraph::OptimizationHint.

If true, orthographic projection will be used for displaying the graph. Defaults to false.

Note: Shadows will be disabled when set to true.

This property was introduced in QtDataVisualization 1.1.

If true, the horizontal axes are changed into polar axes. The x-axis becomes the angular axis and the z-axis becomes the radial axis. Polar mode is not available for bar graphs.

Defaults to false.

This property was introduced in QtDataVisualization 1.2.

See also orthoProjection and radialLabelOffset.

This read-only property contains the latest graph position values along each axis queried using Scene3D::graphPositionQuery. The values are normalized to range [-1, 1]. If the queried position was outside the graph bounds, the values will not reflect the real position, but will instead be some undefined position outside the range [-1, 1]. The value will be undefined until a query is made.

There is no single correct 3D coordinate to match a particular screen position, so to be consistent, the queries are always done against the inner sides of an invisible box surrounding the graph.

Note: Bar graphs only allow querying graph position at the graph floor level, so the y-value is always zero for bar graphs and valid queries can be only made at screen positions that contain the floor of the graph.

This property was introduced in QtDataVisualization 1.2.

See also Scene3D::graphPositionQuery.

This property specifies the normalized horizontal offset for the axis labels of the radial polar axis. The value 0.0 indicates that the labels should be drawn next to the 0-angle angular axis grid line. The value 1.0 indicates that the labels are drawn in their usual place at the edge of the graph background. This property is ignored if the polar property value is false. Defaults to 1.0.

This property was introduced in QtDataVisualization 1.2.

See also polar.

Sets floor reflections on or off. Defaults to false.

Note: Affects only Bars3D. However, in Bars3D graphs holding both positive and negative values, reflections are not supported for custom items that intersect the floor plane. In that case, reflections should be turned off to avoid incorrect rendering.

This property was introduced in QtDataVisualization 1.2.

See also reflectivity.

Sets floor reflectivity. Larger numbers make the floor more reflective. The valid range is [0...1]. Defaults to 0.5.

Note: Affects only Bars3D.

This property was introduced in QtDataVisualization 1.2.

See also reflection.

How the graph will be rendered. Defaults to RenderIndirect.

Note: Antialiasing is not supported in OpenGL ES2 environments in any rendering mode.

Note: Setting the antialiasing property of the graph does not do anything. However, it is set by the graph itself if the current rendering mode uses antialiasing.

See also msaaSamples.

The Scene3D pointer that can be used to manipulate the scene and access the scene elements, such as the active camera.

This property is read-only.

The element selected in the graph.

This property can be used to query the selected element type. The type is valid until a new selection is made in the graph and the selectedElementChanged signal is emitted.

The signal can be used for example for implementing customized input handling, as demonstrated by the Qt Quick 2 Axis Dragging Example.

This property was introduced in QtDataVisualization 1.1.

See also selectedLabelIndex(), selectedAxis(), selectedCustomItemIndex(), selectedCustomItem(), Bars3D::selectedSeries, Scatter3D::selectedSeries, Scene3D::selectionQueryPosition, and QAbstract3DGraph::ElementType.

The active selection mode in the visualization. One of the QAbstract3DGraph::SelectionFlag enum values.

See also QAbstract3DGraph::SelectionFlag.

The quality of shadows. One of the QAbstract3DGraph::ShadowQuality enum values.

See also QAbstract3DGraph::ShadowQuality.

This read-only property indicates whether shadows are supported with the current configuration. OpenGL ES2 configurations do not support shadows.

The active theme of the graph.

See also Theme3D.

Adds a Custom3DItem item to the graph. Graph takes ownership of the added item.

This method was introduced in QtDataVisualization 1.1.

See also removeCustomItems(), removeCustomItem(), and removeCustomItemAt().

Clears selection from all attached series.
