The sprite configuration used when highlighting items in the series.
The sprite configuration used when highlighting items in the series.
Sprite template used for series.
Defaults to: {type: 'rect', fx: {customDuration: {x: 0, y: 0, width: 0, height: 0, radius: 0}}}
Overrides: Ext.chart.series.Series.itemInstancing
Object with the following properties:
Defaults to: {textBaseline: 'middle', textAlign: 'center', font: '14px Helvetica'}
Specifies the presence and position of the labels. The possible values depend on the chart type. For Line charts: 'under' | 'over' | 'rotate'. For Bar charts: 'insideStart' | 'insideEnd' | 'outside'. For Pie charts: 'outside' | 'rotate'. For all charts: 'none' hides the labels.
Default value: 'none'.
The color of the label text.
Default value: '#000' (black).
The name(s) of the field(s) to be displayed in the labels. If your chart has 3 series
that correspond to the fields 'a', 'b', and 'c' of your model and you only want to
display labels for the series 'c', you must still provide an array [null, null, 'c'].
Default value: null.
The font used for the labels.
Default value: '14px Helvetica'.
Either 'horizontal' or 'vertical'. If not set (default), the orientation is inferred from the value of the flipXY property of the series.
Default value: ''.
Optional function for formatting the label into a displayable value.
The arguments to the method are:
text, sprite, config, rendererData, index
Label's renderer is passed the same arguments as renderer plus one extra 'text' argument which comes first.
This cfg has been deprecated
Use 'field' property of label instead. The store record field name to be used for the series labels.
Extra distance value for which the labelOverflow listener is triggered.
Defaults to: 5
A config object containing one or more event handlers to be added to this object during initialization. This
should be a valid listeners config object as specified in the addListener example for attaching
multiple handlers at once.
See the Event guide for more
Note: It is bad practice to specify a listener's config when you are defining a class using Ext.define().
Instead, only specify listeners when you are instantiating your class with Ext.create().
The sprite template used by marker instances on the series.
The sprite template used by marker instances on the series.
This is cyclic used if series have multiple marker sprites.
This is cyclic used if series have multiple marker sprites.
A function that can be provided to set custom styling properties to each rendered element.
It receives (sprite, config, rendererData, index) as parameters.
The sprite affected by the renderer. The visual attributes are in sprite.attr.
The data field is available in sprite.getField().
The sprite configuration. It varies with the series and the type of sprite:
for instance, a Line chart sprite might have just the x and y properties while a Bar
chart sprite also has width and height. A type might be present too. For instance to
draw each marker and each segment of a Line chart, the renderer is called with the
config.type set to either marker or line.
A record with different properties depending on the type of chart.
The only guaranteed property is rendererData.store, the store used by the series.
In some cases, a store may not exist: for instance a Gauge chart may read its value directly
from its configuration; in this case rendererData.store is null and the value is
available in rendererData.value.
The index of the sprite. It is usually the index of the store record associated
with the sprite, in which case the record can be obtained with store.getData().items[index].
If the chart is not associated with a store, the index represents the index of the sprite within
the series. For instance a Gauge chart may have as many sprites as there are sectors in the
background of the gauge, plus one for the needle.
The attributes that have been changed or added. Note: it is usually possible to
add or modify the attributes directly into the config parameter and not return anything,
but returning an object with only those attributes that have been changed may allow for
optimizations in the rendering of some series. Example to draw every other item in red:
renderer: function (sprite, config, rendererData, index) {
if (index % 2 == 0) {
return { strokeStyle: 'red' };
}
}
Whether to show this series in the legend.
Defaults to: true
'true' to display the series in its stacked configuration.
Defaults to: true
Custom style configuration for the sprite used in the series.
Defaults to: {}
This is the cyclic used if the series has multiple sprites.
Defaults to: {}
The human-readable name of the series (displayed in the legend).
The human-readable name of the series (displayed in the legend).
The field used to access the x axis value from the items from the data source.
The field used to access the x axis value from the items from the data source.
Defaults to: {id: 'observable', hooks: {destroy: 'destroy'}}
Overrides: Ext.mixin.Sortable.mixinConfig
Defaults to: 'series'

Get the reference to the current class from which this object was instantiated. Unlike statics,
this.self is scope-dependent and it's meant to be used for dynamic inheritance. See statics
for a detailed comparison
Ext.define('My.Cat', {
statics: {
speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
},
constructor: function() {
alert(this.self.speciesName); // dependent on 'this'
},
clone: function() {
return new this.self();
}
});
Ext.define('My.SnowLeopard', {
extend: 'My.Cat',
statics: {
speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
}
});
var cat = new My.Cat(); // alerts 'Cat'
var snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'
var clone = snowLeopard.clone();
alert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'
Appends an after-event handler.
Same as addListener with order set to 'after'.
The name of the event to listen for.
The method the event invokes.
The scope for fn.
An object containing handler configuration.
Appends a before-event handler. Returning false from the handler will stop the event.
Same as addListener with order set to 'before'.
The name of the event to listen for.
The method the event invokes.
The scope for fn.
An object containing handler configuration.
Adds the specified events to the list of events which this Observable may fire.
This method has been deprecated since 2.0
It's no longer needed to add events before firing.
Appends an event handler to this object. You can review the available handlers by looking at the 'events' section of the documentation for the component you are working with.
Using the options argument, it is possible to combine different types of listeners:
A delayed, one-time listener:
container.addListener('tap', this.handleTap, this, {
single: true,
delay: 100
});
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:
container.addListener({
tap : this.onTap,
swipe: this.onSwipe,
scope: this // Important. Ensure "this" is correct during handler execution
});
One can also specify options for each event handler separately:
container.addListener({
tap : { fn: this.onTap, scope: this, single: true },
swipe: { fn: button.onSwipe, scope: button }
});
See the Events Guide for more.
The name of the event to listen for. May also be an object who's property names are event names.
The method the event invokes. Will be called with arguments given to
fireEvent plus the options parameter described below.
The scope (this reference) in which the handler function is executed. If
omitted, defaults to the object which fired the event.
An object containing handler configuration.
This object may contain any of the following properties:
The scope (this reference) in which the handler function is executed. If omitted, defaults to the object
which fired the event.
The number of milliseconds to delay the invocation of the handler after the event fires.
true to add a handler to handle just the next firing of the event, and then remove itself.
The order of when the listener should be added into the listener queue.
If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.
Available options are before, current and after.
Defaults to: current
Causes the handler to be delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.
Allows you to add a listener onto a element of this component using the elements reference.
Ext.create('Ext.Component', {
listeners: {
element: 'element',
tap: function() {
alert('element tap!');
}
}
});
All components have the element reference, which is the outer most element of the component. Ext.Container also has the
innerElement element which contains all children. In most cases element is adequate.
Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.
// Create a container with a two children; a button and a toolbar
var container = Ext.create('Ext.Container', {
items: [
{
xtype: 'toolbar',
docked: 'top',
title: 'My Toolbar'
},
{
xtype: 'button',
text: 'My Button'
}
]
});
container.addListener({
// Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
delegate: 'button',
tap: function() {
alert('Button tapped!');
}
});
The order of when the listener should be added into the listener queue.
Possible values are before, current and after.
Defaults to: 'current'
Adds listeners to any Observable object (or Element) which are automatically removed when this Component is destroyed.
This method has been deprecated since 2.0
All listeners are now automatically managed where necessary. Simply use addListener.
The item to which to add a listener/listeners.
The event name, or an object containing event name properties.
If the eventName parameter was an event name, this is the handler function.
If the eventName parameter was an event name, this is the scope in which
the handler function is executed.
If the eventName parameter was an event name, this is the
addListener options.
Call the original method that was previously overridden with override,
This method is deprecated as callParent does the same thing.
Ext.define('My.Cat', {
constructor: function() {
alert("I'm a cat!");
}
});
My.Cat.override({
constructor: function() {
alert("I'm going to be a cat!");
var instance = this.callOverridden();
alert("Meeeeoooowwww");
return instance;
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
The arguments, either an array or the arguments object
from the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext.define).
Ext.define('My.Base', {
constructor: function (x) {
this.x = x;
},
statics: {
method: function (x) {
return x;
}
}
});
Ext.define('My.Derived', {
extend: 'My.Base',
constructor: function () {
this.callParent([21]);
}
});
var obj = new My.Derived();
alert(obj.x); // alerts 21
This can be used with an override as follows:
Ext.define('My.DerivedOverride', {
override: 'My.Derived',
constructor: function (x) {
this.callParent([x*2]); // calls original My.Derived constructor
}
});
var obj = new My.Derived();
alert(obj.x); // now alerts 42
This also works with static methods.
Ext.define('My.Derived2', {
extend: 'My.Base',
statics: {
method: function (x) {
return this.callParent([x*2]); // calls My.Base.method
}
}
});
alert(My.Base.method(10)); // alerts 10
alert(My.Derived2.method(10)); // alerts 20
Lastly, it also works with overridden static methods.
Ext.define('My.Derived2Override', {
override: 'My.Derived2',
statics: {
method: function (x) {
return this.callParent([x*2]); // calls My.Derived2.method
}
}
});
alert(My.Derived2.method(10)); // now alerts 40
To override a method and replace it and also call the superclass method, use callSuper. This is often done to patch a method to fix a bug.
The arguments, either an array or the arguments object
from the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.
Consider:
Ext.define('Ext.some.Class', {
method: function () {
console.log('Good');
}
});
Ext.define('Ext.some.DerivedClass', {
method: function () {
console.log('Bad');
// ... logic but with a bug ...
this.callParent();
}
});
To patch the bug in DerivedClass.method, the typical solution is to create an
override:
Ext.define('App.paches.DerivedClass', {
override: 'Ext.some.DerivedClass',
method: function () {
console.log('Fixed');
// ... logic but with bug fixed ...
this.callSuper();
}
});
The patch method cannot use callParent to call the superclass method since
that would call the overridden method containing the bug. In other words, the
above patch would only produce "Fixed" then "Good" in the console log, whereas,
using callParent would produce "Fixed" then "Bad" then "Good".
The arguments, either an array or the arguments object
from the current method, for example: this.callSuper(arguments)
Returns the result of calling the superclass method
This method will return an array containing data coordinated by a specific axis.
Fires the specified event with the passed parameters and execute a function (action)
at the end if there are no listeners that return false.
The name of the event to fire.
Arguments to pass to handers.
Action.
Scope of fn.
Fires the specified event with the passed parameters (minus the event name, plus the options object passed
to addListener).
The first argument is the name of the event. Every other argument passed will be available when you listen for the event.
Firstly, we set up a listener for our new event.
this.on('myevent', function(arg1, arg2, arg3, arg4, options, e) {
console.log(arg1); // true
console.log(arg2); // 2
console.log(arg3); // { test: 'foo' }
console.log(arg4); // 14
console.log(options); // the options added when adding the listener
console.log(e); // the event object with information about the event
});
And then we can fire off the event.
this.fireEvent('myevent', true, 2, { test: 'foo' }, 14);
An event may be set to bubble up an Observable parent hierarchy by calling enableBubble.
The name of the event to fire.
Variable number of parameters are passed to handlers.
Returns false if any of the handlers return false.

the item's rendering Sprite.
the index if sprite is an instancing sprite.
Overrides: Ext.chart.series.Series.getItemForPoint, Ext.chart.series.Cartesian.getItemForPoint, Ext.chart.series.StackedCartesian.getItemForPoint
Returns the value of label.
Specifies the presence and position of the labels. The possible values depend on the chart type. For Line charts: 'under' | 'over' | 'rotate'. For Bar charts: 'insideStart' | 'insideEnd' | 'outside'. For Pie charts: 'outside' | 'rotate'. For all charts: 'none' hides the labels.
Default value: 'none'.
The color of the label text.
Default value: '#000' (black).
The name(s) of the field(s) to be displayed in the labels. If your chart has 3 series
that correspond to the fields 'a', 'b', and 'c' of your model and you only want to
display labels for the series 'c', you must still provide an array [null, null, 'c'].
Default value: null.
The font used for the labels.
Default value: '14px Helvetica'.
Either 'horizontal' or 'vertical'. If not set (default), the orientation is inferred from the value of the flipXY property of the series.
Default value: ''.
Optional function for formatting the label into a displayable value.
The arguments to the method are:
text, sprite, config, rendererData, index
Label's renderer is passed the same arguments as renderer plus one extra 'text' argument which comes first.
Returns the value of labelField.
This method has been deprecated
Use 'field' property of label instead. The store record field name to be used for the series labels.
Performs drawing of this series.
Overrides: Ext.chart.series.Series.getSprites, Ext.chart.series.Cartesian.getSprites
Initialize configuration for this class. a typical example:
Ext.define('My.awesome.Class', {
// The default config
config: {
name: 'Awesome',
isAwesome: true
},
constructor: function(config) {
this.initConfig(config);
}
});
var awesome = new My.awesome.Class({
name: 'Super Awesome'
});
alert(awesome.getName()); // 'Super Awesome'

Get the current class' name in string format.
Ext.define('My.cool.Class', {
constructor: function() {
alert(this.self.getName()); // alerts 'My.cool.Class'
}
});
My.cool.Class.getName(); // 'My.cool.Class'
className
Override members of this class. Overridden methods can be invoked via callParent.
Ext.define('My.Cat', {
constructor: function() {
alert("I'm a cat!");
}
});
My.Cat.override({
constructor: function() {
alert("I'm going to be a cat!");
var instance = this.callParent(arguments);
alert("Meeeeoooowwww");
return instance;
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
As of 2.1, direct use of this method is deprecated. Use Ext.define instead:
Ext.define('My.CatOverride', {
override: 'My.Cat',
constructor: function() {
alert("I'm going to be a cat!");
var instance = this.callParent(arguments);
alert("Meeeeoooowwww");
return instance;
}
});
The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).
This method has been deprecated since 2.1.0
Please use Ext.define instead
