+/**
+ * @author
+ * Joe Kuan
+ *
+ * version 2.4.2
+ *
+ *
+ *
+ * Documentation last updated: 17 Apr 2013
+ *
+ * A much improved & ported from ExtJs 3 Highchart adapter.
+ *
+ * - Supports the latest Highcharts (3.0.0)
+ * - Supports both Sencha ExtJs 4 and Touch 2
+ * - Supports Highcharts animations
+ *
+ * In order to use this extension, you are expected to know how to use Highcharts and Sencha products (ExtJs 4 & Touch 2).
+ *
+ * # Configuring Highcharts Extension
+ * The Highcharts extension requires a few changes from an existing Highcharts configuration. Suppose we already have a
+ * configuration as follows:
+ * @example
+ * var chart = new Highcharts.Chart({
+ * chart: {
+ * renderTo: 'container',
+ * type: 'spline'
+ * },
+ * title: {
+ * text: 'A simple graph'
+ * },
+ * xAxis: {
+ * categories: [ 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul',
+ * 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' ]
+ * },
+ * series: [{
+ * dashStyle: 'DashDot',
+ * data: [54.7, 54.7, 53.9, 54.8, 54.4, 54.2, 52.4, 51.0, 49.0, 47.4, 47.0, 46 ]
+ * }]
+ * });
+ * ## Step 1: Remove data related fields
+ *
+ * The first step is to take out the configuration
+ * object and remove any data related properties such as: *xAxis.categories* and *series[0].data*. Then removes
+ * *chart.renderTo* option as the extension will fill in that property internally. This leaves us with the following config:
+ * @example
+ * chart: {
+ * type: 'spline'
+ * },
+ * title: {
+ * text: 'A simple graph'
+ * },
+ * series: [{
+ * dashStyle: 'DashDot'
+ * }]
+ * ## Step 2: Create chartConfig
+ *
+ * The next step is to create an object called, *chartConfig*, and put the above configuration in it. Then we extract the
+ * series array to an upper level which gives the followings:
+ * @example
+ * series: [{
+ * dashStyle: 'DashDot'
+ * }],
+ * chartConfig: {
+ * chart: {
+ * type: 'spline'
+ * },
+ * title: {
+ * text: 'A simple graph'
+ * }
+ * }
+ * ## Step 3: Create ExtJs Store and data mappings
+ *
+ * Then we create a ExtJs Store object to map the data fields.
+ * @example
+ * Ext.define('SampleData', {
+ * extend: 'Ext.data.Model',
+ * fields: [
+ * {name: 'month', type: 'string'},
+ * {name: 'value', type: 'float'}
+ * ]
+ * });
+ *
+ * var store = Ext.create('Ext.data.Store', {
+ * model: 'SampleData',
+ * proxy: {
+ * type: 'ajax',
+ * url: '/getData.php',
+ * reader: {
+ * type: 'json',
+ * root: 'rows'
+ * }
+ * },
+ * autoLoad: false
+ * });
+ * Then we modify the series array with data mappings to Store; we add *xField* outside the series array
+ * as categories data and *dataIndex* for the y-axis values. For historical reason, we can also use *yField*,
+ * just an alias name for *dataIndex*.
+ * @example
+ * series:[{
+ * dashStyle: 'DashDot',
+ * dataIndex: 'value'
+ * }],
+ * xField: 'month',
+ * store: store,
+ * chartConfig: {
+ * chart: {
+ * ....
+ *
+ * ## Step 4: Create ExtJs Highcharts Component
+ *
+ * The final step is to create a Highcharts component with the whole config as an object specifier.
+ * @example
+ * var win = new Ext.create('Ext.window.Window', {
+ * layout: 'fit',
+ * items: [{
+ * xtype: 'highchart',
+ * series:[{
+ * dashStyle: 'DashDot',
+ * dataIndex: 'value'
+ * }],
+ * xField: 'month',
+ * store: store,
+ * chartConfig: {
+ * chart: {
+ * type: 'spline'
+ * },
+ * title: {
+ * text: 'A simple graph'
+ * }
+ * }
+ * }]
+ * }).show();
+ *
+ * # Updating Highcharts chart properties dynamically
+ * Some of the Highcharts properties cannot be updated interactively such as relocating legend box,
+ * switching column charts stacking mode. The only way is to manually destroy and create the whole chart again.
+ * In Highcharts extension, this can be done in an easier fashion. The Highcharts component itself
+ * contains a *chartConfig* object which holds the existing native Highcharts configurations. At runtime,
+ * options inside *chartConfig* can be modified and call method *draw* which interally destroys and
+ * creates a new chart. As a result, the chart appears as a dynamic smooth update
+ * @example
+ * var chart = new Ext.create('Chart.ux.Highcharts', {
+ * ....
+ * });
+ * chart.chartConfig.plotOptions.column.stacking = 'normal';
+ * chart.draw();
+ *
+ * # Mapping between JsonStore and series data
+ * The data mapping between JsonStore and chart series option is quite straightforward. Please refers
+ * to the desired {@link Chart.ux.Highcharts.Serie} class and {@link Chart.ux.Highcharts.Serie#method-getData}
+ * method for more details on data mapping.
+ *

+/**
+ * # Plotting Pie Series
+ * There are two ways to plot pie chart from record data: a data point per record and
+ * total values of all the records
+ *
+ * ## Data point per record
+ * Pie series uses two options for mapping category name and data fields:
+ * *categoryField* and *dataField*, (This is historical reason instead of
+ * using *xField* and *dataIndex*). Suppose we have data model in the following format:
+ *
+ *
+ *
+ *
productName
sold
+ *
Product A
15,645,242
+ *
Product B
22,642,358
+ *
Product C
21,432,330
+ *
+ *
+ * Then we can define the series data as:
+ *
+ * series: [{
+ * type: 'pie',
+ * categoryField: 'productName',
+ * dataField: 'sold'
+ * }]
+ *
+ * # Data point as total value of all the records
+ * Instead of mapping *dataField* and *categorieField* fields to the store record for each
+ * pie data point, this approach uses the total value of a category as a data point.
+ * E.g. we have a class of pupils with a set of subject scores
+ *
+ *
+ *
Name
English
Math
Science
+ *
Joe
77
81
78
+ *
David
67
56
69
+ *
Nora
44
50
39
+ *
+ *
+ * All we want is to plot distribution of total scores for each subject. Hence, we define
+ * the pie series as follows:
+ * series: [{
+ * type: 'pie',
+ * useTotals: true,
+ * column: [ 'english', 'math', 'science' ]
+ * }]
+ * whereas the server-side should return JSON data as follows:
+ * { "root": [{ "english": 77, "math": 81, "science": 78 },
+ * { "english": 67, "math": 56, "science": 69 },
+ * { "english": 44, "math": 50, "science": 39 },
+ * ..... ]
+ * }
+ * and the data model for the store is defined as follows:
+ * Ext.define('ExamResults', {
+ * extend: 'Ext.data.Model',
+ * fields: [
+ * {name: 'english', type: 'int'},
+ * {name: 'math', type: 'int'},
+ * {name: 'science', type: 'int'}
+ * ]
+ * });
+ *
+ * # Multiple Pie Series (Donut chart)
+ * A donut chart is really two pie series which a second pie series lay outside of the
+ * first series. The second series is subcategory data of the first series.
+ * Suppose we want to plot a more detail chart with the breakdown of sold items into regions:
+ *
+ *
+ *
productName
sold
Europe
Asia
Americas
+ *
Product A
15,645,242
10,432,542
2,425,432
2,787,268
+ *
Product B
22,642,358
4,325,421
4,325,321
13,991,616
+ *
Product C
21,432,330
2,427,431
6,443,234
12,561,665
+ *
+ *
+ * The data model for the donut chart store should be refined with fields: productName,
+ * sold and region. The rows returning from the store should look like:
+ *
+ *
+ *
productName
sold
region
+ *
Product A
10,432,542
Europe
+ *
Product A
2,425,432
Asia
+ *
Product A
2,787,268
Americas
+ *
Product B
4,325,421
Europe
+ *
Product B
4,325,321
Asia
+ *
+ *
+ The series definition for the donut chart should look like this:
+ * series: [{
+ * // Inner pie series
+ * type: 'pie',
+ * categoryField: 'productName',
+ * dataField: 'sold',
+ * size: '60%',
+ * totalDataField: true
+ * }, {
+ * // Outer pie series
+ * type: 'pie',
+ * categoryField: 'region',
+ * dataField: 'sold',
+ * innerSize: '60%',
+ * size: '75%'
+ * }]
+ * The *totalDataField* informs the first series to take the sum of *dataField* (sold)
+ * on entries with the same *categoryField* value, whereas the second series displays
+ * a section on each region (i.e. each record). The *innerSize* is just the Highcharts
+ * option to make the outer pie series appear as ring form.
+ *
+ * If you want to have a fix set of colours in the outer ring along each slice, then
+ * you can create an extra field in your store for the color code and use the
+ * *colorField* option to map the field.

+ * Serie class is the base class for all the series types. Users shouldn't use any of the
+ * series classes directly, they are created internally from Chart.ux.Highcharts depending on the
+ * series configuration.
+ *
+ * Serie class is a general class for series data representation.
+ * # Mapping data fields
+ * In the Highcharts extension, the series option is declared outside of chartConfig, so as the *xField*.
+ * There is a subtle difference for declaring xField outside or inside a series. For example:
+ *
+ * series:[{
+ * name: 'Share A',
+ * type: 'line',
+ * yField: 'sharePriceA'
+ * }, {
+ * name: 'Share B',
+ * type: 'line',
+ * yField: 'sharePriceB'
+ * }],
+ * xField: 'datetime',
+ * ....
+ * This means both series share the same categories and each series has it own set of y-values.
+ * In this case, the datetime field can be either string or numerical representation of date time.
+ * series:[{
+ * name: 'Share A',
+ * type: 'line',
+ * yField: 'sharePriceA',
+ * xField: 'datetimeA'
+ * }, {
+ * name: 'Share B',
+ * type: 'line',
+ * yField: 'sharePriceB',
+ * xField: 'datetimeB'
+ * }],
+ * This means both series have their own (x,y) data. In this case, the xField must refer to numerical values.
+ *
+ * # Mapping multiple series with irregular datasets
+ * Suppose we have 3 series with different set of data points. To map the store with the series, first
+ * the store is required to return Json data in the following format:
+ * { root: [
+ * series1: [ [ 1, 3 ], [ 2, 5 ], [ 7, 1 ] ],
+ * series2: [ [ 2, 4 ], [ 5, 7 ] ],
+ * series3: [ [ 1, 8 ], [ 4, 6 ], [ 5, 1 ], [ 9, 4 ] ]
+ * ]
+ * }
+ *
+ * Then use {@link Chart.ux.Highcharts.Serie#cfg-dataIndex} to map the series data array
+ * series: [{
+ * name: 'Series A',
+ * dataIndex: 'series1'
