目标值实现echarts 75%配置项内容和展示

在仪表盘上需要增加目标值，是否能实现仪表轨迹的效果（如上传图片），麻烦各位大神指点迷津。

      var angle = [220, -40],
    splitNum = 10,
    alertVal = 70,
    targetVal = 69,
    curVal = 67.8;
var option = {
    backgroundColor: '#fff',
    tooltip: {
        show: false,
        formatter: "{a} <br/>{b} : {c}%"
    },
        title:{
        
        subtext: '指标评分|制度评分',
        text: (targetVal) + '         '+(curVal),
        x: 'center',
        y: '60%',
  
        subtextStyle: {
            color: '#3da1ee',
            fontSize: 25
        },
              textStyle: {
