Chart（图表）说明
图表的类型（Chart types）
说明
three types of charts: cartesian, polar, and spacefilling（笛卡尔、极坐标和空间填充）
cartesian chart
Ext.chart.CartesianChart (xtype: cartesian or chart)
A cartesian chart has two directions: X and Y. By default, X is horizontal and Y is vertical. Charts that use the cartesian coordinates are column, bar, area, line, and scatter
polar chart
Ext.chart.PolarChart (xtype: polar)
These charts have two axes: angular and radial. Charts that plot values using the
polar coordinates are pie and radar
spacefilling chart
Ext.chart.SpaceFillingChart (xtype: spacefilling)
These charts fill the complete area of the chart
图表的组成
Series定义图形的内容
Axes定义图表的轴
Legend定义图表的图例
Labels定义图表的标签
Interactions定义图表的交互
Sprite定义图表的标题等元素
定义Legend
legend: {
docked: 'left' //可取值left, top, bottom, right
}
使用前准备
如果是直接引入的CSS和JS方式进行ExtJS开发
将build目录下的packages目录复制到开发目录下
需要额外引入图形组件的css和js文件
<!-- 引入CSS文件 -->
<link rel="stylesheet" href=/packages/charts/modern/modern-material/resources/charts-all-debug.css">
<!-- 引入JS文件 -->
<script src="/packages/charts/modern/charts-debug.js"></script>
常用图表
折线图（Line Chart）
语法：
Ext.create('Ext.chart.CartesianChart',{
series: [{
type: 'line',
xField: 'name',
yField: 'G1'
}]
//render, legend and other properties
});
条形图（Bar Chart）
Ext.create('Ext.chart.CartesianChart',{
series: [{
type: 'bar',
xField: 'name',
yField: 'G1'
}]
//render, legend and other properties
});
饼图（Pie Chart）
Ext.chart.PolarChart (xtype: polar)
语法：
Ext.create('Ext.chart.PolarChart', {
series: [{
Type: 'pie'
..
}]
//render and other properties.
});
面积图（Area Chart）
Ext.create('Ext.chart.CartesianChart',{
