Creates a Bar Chart. A Bar Chart is a useful visualization technique to display quantitative information for different categories that can show some progression (or regression) in the dataset. As with all other series, the Bar Series must be appended in the series Chart array configuration. See the Chart documentation for more information. A typical configuration object for the bar series could be:

var store = Ext.create('Ext.data.JsonStore', {
    fields: ['name', 'data1', 'data2', 'data3', 'data4', 'data5'],
    data: [
        { 'name': 'metric one',   'data1':10, 'data2':12, 'data3':14, 'data4':8,  'data5':13 },
        { 'name': 'metric two',   'data1':7,  'data2':8,  'data3':16, 'data4':10, 'data5':3  },
        { 'name': 'metric three', 'data1':5,  'data2':2,  'data3':14, 'data4':12, 'data5':7  },
        { 'name': 'metric four',  'data1':2,  'data2':14, 'data3':6,  'data4':1,  'data5':23 },
        { 'name': 'metric five',  'data1':27, 'data2':38, 'data3':36, 'data4':13, 'data5':33 }
    ]
});

Ext.create('Ext.chart.Chart', {
    renderTo: Ext.getBody(),
    width: 500,
    height: 300,
    animate: true,
    store: store,
    axes: [{
        type: 'Numeric',
        position: 'bottom',
        fields: ['data1'],
        label: {
            renderer: Ext.util.Format.numberRenderer('0,0')
        },
        title: 'Sample Values',
        grid: true,
        minimum: 0
    }, {
        type: 'Category',
        position: 'left',
        fields: ['name'],
        title: 'Sample Metrics'
    }],
    series: [{
        type: 'bar',
        axis: 'bottom',
        highlight: true,
        tips: {
          trackMouse: true,
          width: 140,
          height: 28,
          renderer: function(storeItem, item) {
            this.setTitle(storeItem.get('name') + ': ' + storeItem.get('data1') + ' views');
          }
        },
        label: {
          display: 'insideEnd',
            field: 'data1',
            renderer: Ext.util.Format.numberRenderer('0'),
            orientation: 'horizontal',
            color: '#333',
            'text-anchor': 'middle'
        },
        xField: 'name',
        yField: ['data1']
    }]
});

In this configuration we set bar as the series type, bind the values of the bar to the bottom axis and set the xField or category field to the name parameter of the store. We also set highlight to true which enables smooth animations when bars are hovered. We also set some configuration for the bar labels to be displayed inside the bar, to display the information found in the data1 property of each element store, to render a formated text with the Ext.util.Format we pass in, to have an horizontal orientation (as opposed to a vertical one) and we also set other styles like color, text-anchor, etc.

Parameters

  • o : Object/String

    Either an object with event names as properties with a value of true or the first event name string if multiple event names are being passed as separate parameters. Usage:

    this.addEvents({
        storeloaded: true,
        storecleared: true
    });

Available since: 4.0.6

Parameters

Returns

( eventName, fn, [scope], [options] )
Appends an event handler to this object. ...

Appends an event handler to this object.

Available since: 1.1.0

Parameters

  • eventName : String

    The name of the event to listen for. May also be an object who's property names are event names.

  • fn : Function

    The method the event invokes. Will be called with arguments given to fireEvent plus the options parameter described below.

  • scope : Object (optional)

    The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

  • options : Object (optional)

    An object containing handler configuration.

    Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

    This object may contain any of the following properties:

    • scope : Object

      The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

    • delay : Number

      The number of milliseconds to delay the invocation of the handler after the event fires.

    • single : Boolean

      True to add a handler to handle just the next firing of the event, and then remove itself.

    • buffer : Number

      Causes the handler to be scheduled to run in an Ext.util.DelayedTask 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.

    • target : Observable

      Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

    • element : String

      This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

      This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

      new Ext.panel.Panel({
          title: 'The title',
          listeners: {
              click: this.handlePanelClick,
              element: 'body'
          }
      });
      

    Combining Options

    Using the options argument, it is possible to combine different types of listeners:

    A delayed, one-time listener.

    myPanel.on('hide', this.handleClick, this, {
        single: true,
        delay: 100
    });
    

    Attaching multiple handlers in 1 call

    The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

    myGridPanel.on({
        cellClick: this.onCellClick,
        mouseover: this.onMouseOver,
        mouseout: this.onMouseOut,
        scope: this // Important. Ensure "this" is correct during handler execution
    });
    

    One can also specify options for each event handler separately:

    myGridPanel.on({
        cellClick: {fn: this.onCellClick, scope: this, single: true},
        mouseover: {fn: panel.onMouseOver, scope: panel}
    });

Available since: 4.0.0

Parameters

  • item : Ext.util.Observable/Ext.Element

    The item to which to add a listener/listeners.

  • ename : Object/String

    The event name, or an object containing event name properties.

  • fn : Function (optional)

    If the ename parameter was an event name, this is the handler function.

  • scope : Object (optional)

    If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

  • opt : Object (optional)

    If the ename parameter was an event name, this is the addListener options.

Parameters

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. ...

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

Example:

Ext.override(Ext.form.field.Base, {
    //  Add functionality to Field's initComponent to enable the change event to bubble
    initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
        this.enableBubble('change');
    }),

    //  We know that we want Field's events to bubble directly to the FormPanel.
    getBubbleTarget : function() {
        if (!this.formPanel) {
            this.formPanel = this.findParentByType('form');
        }
        return this.formPanel;
    }
});

var myForm = new Ext.formPanel({
    title: 'User Details',
    items: [{
        ...
    }],
    listeners: {
        change: function() {
            // Title goes red if form has been modified.
            myForm.header.setStyle('color', 'red');
        }
    }
});

Available since: 4.0.2

Parameters

  • item : Ext.util.Observable/Ext.Element

    The item to which to add a listener/listeners.

  • ename : Object/String

    The event name, or an object containing event name properties.

  • fn : Function (optional)

    If the ename parameter was an event name, this is the handler function.

  • scope : Object (optional)

    If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

  • opt : Object (optional)

    If the ename parameter was an event name, this is the addListener options.

( item, ename, [fn], [scope] )
Shorthand for removeManagedListener. ...

Shorthand for removeManagedListener.

Removes listeners that were added by the mon method.

Available since: 4.0.2

Parameters

  • item : Ext.util.Observable/Ext.Element

    The item from which to remove a listener/listeners.

  • ename : Object/String

    The event name, or an object containing event name properties.

  • fn : Function (optional)

    If the ename parameter was an event name, this is the handler function.

  • scope : Object (optional)

    If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

( eventName, fn, [scope], [options] )
Shorthand for addListener. ...

Shorthand for addListener.

Appends an event handler to this object.

Available since: 1.1.0

Parameters

  • eventName : String

    The name of the event to listen for. May also be an object who's property names are event names.

  • fn : Function

    The method the event invokes. Will be called with arguments given to fireEvent plus the options parameter described below.

  • scope : Object (optional)

    The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

  • options : Object (optional)

    An object containing handler configuration.

    Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

    This object may contain any of the following properties:

    • scope : Object

      The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

    • delay : Number

      The number of milliseconds to delay the invocation of the handler after the event fires.

    • single : Boolean

      True to add a handler to handle just the next firing of the event, and then remove itself.

    • buffer : Number

      Causes the handler to be scheduled to run in an Ext.util.DelayedTask 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.

    • target : Observable

      Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

    • element : String

      This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

      This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

      new Ext.panel.Panel({
          title: 'The title',
          listeners: {
              click: this.handlePanelClick,
              element: 'body'
          }
      });
      

    Combining Options

    Using the options argument, it is possible to combine different types of listeners:

    A delayed, one-time listener.

    myPanel.on('hide', this.handleClick, this, {
        single: true,
        delay: 100
    });
    

    Attaching multiple handlers in 1 call

    The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

    myGridPanel.on({
        cellClick: this.onCellClick,
        mouseover: this.onMouseOver,
        mouseout: this.onMouseOut,
        scope: this // Important. Ensure "this" is correct during handler execution
    });
    

    One can also specify options for each event handler separately:

    myGridPanel.on({
        cellClick: {fn: this.onCellClick, scope: this, single: true},
        mouseover: {fn: panel.onMouseOver, scope: panel}
    });
