echart的简单应用

1.引入文件

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Document</title>
  <script src="libs/echarts/echarts.min.js"></script>
</head>
<body>
  
</body>
</html>

2.定义一个div设个id值

<div ></div>

3.js实现（重要的是option根据API设置属性方法）

var dChart = echarts.init(document.getElementById('demoChart'));

var option = {
          ...
       	   title: {
             ....
           },
	  grid: {
            ....
	  },
         series:[
         .....
         ]
      ....
}

   dChart.setOption(option);

下面是一个完整的实例自己引好echarts.min.js

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
     <script type="text/javascript" src='echarts.min.js'></script>
</head>
<body>
    <div ></div>
    <script type="text/javascript">
var rankChart = echarts.init(document.getElementById('rankChart'));
       var option = {
           title: {
                 text: 'top10',
                 top: 20,
                 left:20
           },
            grid: {
                left: '3%',
                right: '4%',
                bottom: '3%',
                containLabel: true
            },
            xAxis:[
                   {
                    type: 'value',
                    axisLine:{
                       show:false
                     },
                    axisTick:{
                       show:false  
                    },
                  splitLine:{

                            2,
                           type:'dotted'

                     },

                    },
