先看一下效果图:
现在显示的是三条曲线,可以通过修改TipsChart.js来实现线的条数,运用Ext,首先需要的就是引入Ext中的相关文件,这个就不提了,相信对Ext有所了解的都知道需要引那几个文件
下面贴上代码:

TipsChart.js
[html]
Ext.require('Ext.chart.*');
Ext.require('Ext.layout.container.Fit');
Ext.onReady(function () {
var panel1 = Ext.create('widget.panel', {
width: 800,
height: 400,
title: '曲线图',
renderTo: Ext.getBody(),
layout: 'fit',
items: [{
xtype: 'chart',
animate: true,
shadow: true,
store: store1,
legend: {
position: 'right'
},
axes: [{
type: 'Numeric',
minimum: 0,
position: 'left',
fields: ['2011', '2012', '2013'],
title: '百分比',
minorTickSteps: 1,
grid: {
odd: {
opacity: 1,
fill: '#ddd',
stroke: '#bbb',
'stroke-width': 0.5
}
}
}, {
type: 'Category',
position: 'bottom',
fields: 'name',
title: '2013年物业曲线图'
}],
series: [{
type: 'line',
axis: 'left',
gutter: 80,
xField: 'name',
yField: '2011',
markerConfig: {
type: 'circle',
'stroke-width': 0
}
},{
type: 'line',
axis: 'left',
smooth: true,
xField: 'name',
yField: '2012',
markerConfig: {
type: 'circle',
'stroke-width': 0
}
},{
type: 'line',
axis: 'left',
smooth: true,
xField: 'name',
yField: '2013',
markerConfig: {
type: 'circle',
'stroke-width': 0
}
}]
}]
});
});
其中Ext中自带的example-data.js文件我做了修改:
[html]
Ext.onReady(function() {
window.generateData = function(n, floor){
var data = [],i;
for (i = 0; i < (n || 12); i++) {
data.push({
name: i+1+'月份',
2011: Math.floor(Math.max(Math.random() * 100)),
2012: Math.floor(Math.max(Math.random() * 100)),
2013: Math.floor(Math.max(Math.random() * 100))
});
}
return data;
};
window.store1 = Ext.create('Ext.data.JsonStore', {
fields: ['name', '2011', '2012', '2013'],
data: generateData()
});
});
好了,所有代码已上传
