The fields of model to bind to this axis.

For example if you have a data set of lap times per car, each having the fields: 'carName', 'avgSpeed', 'maxSpeed'. Then you might want to show the data on chart with ['carName'] on Name axis and ['avgSpeed', 'maxSpeed'] on Speed axis.

Available since: 4.1.0

The grid configuration enables you to set a background grid for an axis. If set to true on a vertical axis, vertical lines will be drawn. If set to true on a horizontal axis, horizontal lines will be drawn. If both are set, a proper grid with horizontal and vertical lines will be drawn.

You can set specific options for the grid configuration for odd and/or even lines/rows. Since the rows being drawn are rectangle sprites, you can set to an odd or even property all styles that apply to Ext.draw.Sprite. For more information on all the style properties you can set please take a look at Ext.draw.Sprite. Some useful style properties are opacity, fill, stroke, stroke-width, etc.

The possible values for a grid option are then true, false, or an object with { odd, even } properties where each property contains a sprite style descriptor object that is defined in Ext.draw.Sprite.

For example:

axes: [{
    type: 'Numeric',
    position: 'left',
    fields: ['data1', 'data2', 'data3'],
    title: 'Number of Hits',
    grid: {
        odd: {
            opacity: 1,
            fill: '#ddd',
            stroke: '#bbb',
            'stroke-width': 1
        }
    }
}, {
    type: 'Category',
    position: 'bottom',
    fields: ['name'],
    title: 'Month of the Year',
    grid: true
}]

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() {

});


Ext.define('My.SnowLeopard', {

Overrides: Ext.chart.axis.Axis.applyData

Call the original method that was previously overridden with override

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callOverridden();

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Available since: 4.0.0

Parameters

• args : Array/Arguments

  The arguments, either an array or the arguments object from the current method, for example: this.callOverridden(arguments)

Returns

• Object

  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.

Available since: 4.0.0

Parameters

• args : Array/Arguments

  The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

Returns

• Object

  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".

Available since: Ext JS 4.1.3

Parameters

• args : Array/Arguments

Get the reference to the class from which this object was instantiated. Note that unlike self, this.statics() is scope-independent and it always returns the class from which it was called, regardless of what this points to during run-time

    statics: {
        totalCreated: 0,
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

        alert(statics.speciesName);     // always equals to 'Cat' no matter what 'this' refers to
                                        // equivalent to: My.Cat.speciesName

Parameters

• fn : Object
• scope : Object

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!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

As of 4.1, 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!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

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).
