本章节介绍百度echarts 嵌套环形图实例,具体操作步骤如下:

嵌套环形图实例

1,新建静态页面demo.html,并引入echarts的js库,在这里我们引入的是网络地址

<script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/echarts-all-3.js"></script>

2,环形图容器html代码,只需一行html代码

div id="container" style="height: 500px"></div>

环形容器高度为500px,宽度默认,并且div的id号为container,在接下来初始化环形图的时候会用到。

3,javascript实现代码

<script type="text/javascript">
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
var app = {};
var option = null;
app.title = '嵌套环形图';

option = {
    tooltip: {
        trigger: 'item',
        formatter: "{a} <br/>{b}: {c} ({d}%)"
    },
    legend: {
        orient: 'vertical',
        x: 'left',
        data:['直达','营销广告','搜索引擎','邮件营销','联盟广告','视频广告','百度','谷歌','必应','其他']
    },
    series: [
        {
            name:'访问来源',
            type:'pie',
            selectedMode: 'single',
            radius: [0, '30%'],

            label: {
                normal: {
                    position: 'inner'
                }
            },
            labelLine: {
                normal: {
                    show: false
                }
            },
            data:[
                {value:335, name:'直达', selected:true},
                {value:679, name:'营销广告'},
                {value:1548, name:'搜索引擎'}
            ]
        },
        {
            name:'访问来源',
            type:'pie',
            radius: ['40%', '55%'],

            data:[
                {value:335, name:'直达'},
                {value:310, name:'邮件营销'},
                {value:234, name:'联盟广告'},
                {value:135, name:'视频广告'},
                {value:1048, name:'百度'},
                {value:251, name:'谷歌'},
                {value:147, name:'必应'},
                {value:102, name:'其他'}
            ]
        }
    ]
};

 
 
 
if (option && typeof option === "object") {
    myChart.setOption(option, true);
}
       </script>

4,用浏览器打开demo.html,效果如下

5,demo.html完整代码

<!DOCTYPE html>
<head>
       <meta charset="utf-8">
   </head>
   <body >
       <div id="container" style="height: 500px"></div>
        
       <!-- V型知识库 www.vxzsk.com -->
        
       <script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/echarts-all-3.js"></script>
        
       <script type="text/javascript">
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
var app = {};
var option = null;
app.title = '嵌套环形图';

option = {
    tooltip: {
        trigger: 'item',
        formatter: "{a} <br/>{b}: {c} ({d}%)"
    },
    legend: {
        orient: 'vertical',
        x: 'left',
        data:['直达','营销广告','搜索引擎','邮件营销','联盟广告','视频广告','百度','谷歌','必应','其他']
    },
    series: [
        {
            name:'访问来源',
            type:'pie',
            selectedMode: 'single',
            radius: [0, '30%'],

            label: {
                normal: {
                    position: 'inner'
                }
            },
            labelLine: {
                normal: {
                    show: false
                }
            },
            data:[
                {value:335, name:'直达', selected:true},
                {value:679, name:'营销广告'},
                {value:1548, name:'搜索引擎'}
            ]
        },
        {
            name:'访问来源',
            type:'pie',
            radius: ['40%', '55%'],

            data:[
                {value:335, name:'直达'},
                {value:310, name:'邮件营销'},
                {value:234, name:'联盟广告'},
                {value:135, name:'视频广告'},
                {value:1048, name:'百度'},
                {value:251, name:'谷歌'},
                {value:147, name:'必应'},
                {value:102, name:'其他'}
            ]
        }
    ]
};

 
 
 
if (option && typeof option === "object") {
    myChart.setOption(option, true);
}
       </script>
   </body>
</html>
