/**
* The Ext.chart package provides the capability to visualize data.
* Each chart binds directly to a {@link Ext.data.Store store} enabling automatic updates of the chart.
* A chart configuration object has some overall styling options as well as an array of axes
* and series. A chart instance example could look like this:
*
* Ext.create('Ext.chart.CartesianChart', {
* width: 800,
* height: 600,
* animation: {
* easing: 'backOut',
* duration: 500
* },
* store: store1,
* legend: {
* position: 'right'
* },
* axes: [
* // ...some axes options...
* ],
* series: [
* // ...some series options...
* ]
* });
*
* In this example we set the `width` and `height` of a chart; We decide whether our series are
* animated or not and we select a store to be bound to the chart; We also set the legend to the right part of the
* chart.
*
* You can register certain interactions such as {@link Ext.chart.interactions.PanZoom} on the chart by specify an
* array of names or more specific config objects. All the events will be wired automatically.
*
* You can also listen to series `itemXXX` events on both chart and series level.
*
* For example:
*
* Ext.create('Ext.chart.CartesianChart', {
* plugins: {
* ptype: 'chartitemevents',
* moveEvents: true
* },
* store: {
* fields: ['pet', 'households', 'total'],
* data: [
* {pet: 'Cats', households: 38, total: 93},
* {pet: 'Dogs', households: 45, total: 79},
* {pet: 'Fish', households: 13, total: 171}
* ]
* },
* axes: [{
* type: 'numeric',
* position: 'left'
* }, {
* type: 'category',
* position: 'bottom'
* }],
* series: [{
* type: 'bar',
* xField: 'pet',
* yField: 'households',
* listeners: {
* itemmousemove: function (series, item, event) {
* console.log('itemmousemove', item.category, item.field);
* }
* }
* }, {
* type: 'line',
* xField: 'pet',
* yField: 'total',
* marker: true
* }],
* listeners: { // Listen to itemclick events on all series.
* itemclick: function (chart, item, event) {
* console.log('itemclick', item.category, item.field);
* }
* }
* });
*
* For more information about the axes and series configurations please check the documentation of
* each series (Line, Bar, Pie, etc).
*

* (no extra properties other than `type`), you can alternately specify
* only the type as a String rather than the full Object:

*
* The current supported interaction types include:

* - {@link Ext.chart.interactions.PanZoom panzoom} - allows pan and zoom of axes
* - {@link Ext.chart.interactions.ItemHighlight itemhighlight} - allows highlighting of series data points
* - {@link Ext.chart.interactions.ItemInfo iteminfo} - allows displaying details of a data point in a popup panel
* - {@link Ext.chart.interactions.Rotate rotate} - allows rotation of pie and radar series
