Let us take a look at the official website first: https://www.echartsjs.com/zh/index.html

Click For example, you can see various visual charts in the picture above. Select one of the charts:

After opening, the code is on the left and the chart on the right:

app.title = '环形图';
option = {
    tooltip: {
        trigger: 'item',
        formatter: "{a} <br/>{b}: {c} ({d}%)"
    },
    legend: {
        orient: &#39;vertical&#39;,
        x: &#39;left&#39;,
        data:[&#39;直接访问&#39;,&#39;邮件营销&#39;,&#39;联盟广告&#39;,&#39;视频广告&#39;,&#39;搜索引擎&#39;]
    },
    series: [
        {
            name:&#39;访问来源&#39;,
            type:&#39;pie&#39;,
            radius: [&#39;50%&#39;, &#39;70%&#39;],
            avoidLabelOverlap: false,
            label: {
                normal: {
                    show: false,
                    position: &#39;center&#39;
                },
                emphasis: {
                    show: true,
                    textStyle: {
                        fontSize: &#39;30&#39;,
                        fontWeight: &#39;bold&#39;
                    }
                }
            },
            labelLine: {
                normal: {
                    show: false
                }
            },
            data:[
                {value:335, name:&#39;直接访问&#39;},
                {value:310, name:&#39;邮件营销&#39;},
                {value:234, name:&#39;联盟广告&#39;},
                {value:135, name:&#39;视频广告&#39;},
                {value:1548, name:&#39;搜索引擎&#39;}
            ]
        }
    ]
};

Then you only need a few steps to use it:

1. Local installation:

You can use npm to install ECharts:

npm install echarts

2. Introduce echarts into index.html

import echarts from 'echarts'

3. Write a div container to host the chart:

<div class="hccalone">
       <div  id="teamLeader" style="float:left;width:100%;height: 300px"></div>
</div>

Set a div in the above code (set the height, size and other attributes, set An id)

4. Write a method to initialize the chart code (copy and paste the code from the official website document directly and modify the container id and the values ​​of each part):

getTeamLeader(){
            var myChart = echarts.init(document.getElementById('teamLeader'));
            myChart.setOption({
              title : {
                text: '团队考核情况',
                x:'center'
            },
            tooltip: {
                trigger: 'item',
                formatter: "{a} <br/>{b}: {c} ({d}%)"
            },
            legend: {
                orient: &#39;vertical&#39;,
                x: &#39;left&#39;,
                data:[&#39;已完成&#39;,&#39;未完成&#39;]
            },
            series: [
                {
                    name:&#39;访问来源&#39;,
                    type:&#39;pie&#39;,
                    radius: [&#39;50%&#39;, &#39;70%&#39;],
                    avoidLabelOverlap: false,
                    label: {
                        normal: {
                            show: false,
                            position: &#39;center&#39;
                        },
                        emphasis: {
                            show: true,
                            textStyle: {
                                fontSize: &#39;30&#39;,
                                fontWeight: &#39;bold&#39;
                            }
                        }
                    },
                    labelLine: {
                        normal: {
                            show: false
                        }
                    },
                    data:[
                        {value:50, name:&#39;已完成&#39;},
                        {value:50, name:&#39;未完成&#39;}
                    ]
                }
            ]
          });
