漏刻有时数据可视化Echarts组件开发(15):3/4环图的解决方案

 var myChart = echarts.init(document.getElementById(id));
    var pass_rate = parseFloat(dataList[0].value / toNo * 100).toFixed(2);
    var average = parseFloat(dataList[1].value / toNo * 100).toFixed(2)
    var average1 = parseFloat(dataList[2].value / toNo * 100).toFixed(2)
    var average2 = parseFloat(dataList[3].value / toNo * 100).toFixed(2)
    var average3 = parseFloat(dataList[4].value / toNo * 100).toFixed(2)
    var total = 100;

    var option = {
   
        color: ['#ed0f64', '#f48897', '#c3dcf2', '#008ed2', '#0064aa'],
