最近要用到图表展示，想了想，还是首选Echarts，HighCharts和D3.js备用吧，
而项目中也用到了AngularJS，所以需要把Echarts引入到AngularJs中一起使用，
试了试，最方便的还是用指令，（虽然指令有点不好调，用了再说）。
1、引入angular.js
2、引入echarts.js
3、引入jquery.js---可以省略
4、直接上代码：
<!DOCTYPE html >
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

一个Demo，就不按格式写了！
以上！
自定义数据展示颜色：
series:[
{
name:'已使用',
type:'bar',
stack:'存储空间',
label:{
normal:{
show:true,
position:'insideRight'
}
},
barWidth:'80%',
data:[
{
value:100,
itemStyle:{
normal:{
color: 3>2 ? '#CDCD19':'#00FA67'
}
}
},
{
value:200,
itemStyle:{
normal:{
color: 1>2 ? '#CDCD19':'#00FA67'
}
}
},
{
value:300,
itemStyle:{
normal:{
color: 3>2 ? '#CDCD19':'#00FA67'
}
}
},
{
value:260,
itemStyle:{
normal:{
color: 1>2 ? '#CDCD19':'#00FA67'
}
}
},
50,120]
},
{
name:'剩余',
type:'bar',
stack:'存储空间',
label:{
normal:{

}
},
itemStyle:{
