echarts水波球特效（附带外边框进度条）_水波球插件

这里用到了echarts的liquidFill图表，需要加载liquidFill插件 

npm i echarts-liquidFill --save

1. 在main.js入口文件中引入

也可通过script标签形式引入 

<script src="http://echarts.baidu.com/resource/echarts-liquidfill-1.0.4/dist/echarts-liquidfill.js" type="text/javascript" charset="utf-8"></script>

 2.option配置如下(可根据需要自行配置，大概的配置点已经注释出来了)

    chart.setOption({
        // backgroundColor: "#050038",
        title: {
          text: `总完成`,
          left: "center",
          top: "100",
          textStyle: {
            fontWeight: "normal",
            fontSize: 20,
            color: "rgb(0,0,0)"
          },
          subtext: `${this.progress.num}%`, //副标题
          subtextStyle: {
            fontWeight: "bold",
            fontSize: 40,
            color: "rgb(0,0,0)"
          }
        },

              this.progress.num / 100,
              this.progress.num / 100
            ], // data个数代表波浪数

            label: {
              normal: {
                show: false, //不显示label  用副标题代替了
                formatter: (0.5 * 100).toFixed(0) + "%",
                textStyle: {
                  fontSize: 38,

              }
            },
