左边的是在echarts里找的样式，右边是经过修改后的样式

echarts的代码

option = {
  color: ['#67F9D8', '#FFE434', '#56A3F1', '#FF917C'],
  title: {
    text: 'Customized Radar Chart'
  },

      axisLine: {

        padding: [3, 5]
      }
    }
  ],
  series: [
    {
      type: 'radar',
      emphasis: {
        lineStyle: {
          width: 4

      data: [

修改后的代码

 let mychart = echarts.init(document.getElementById("main"));
      let option = {
        color: ["#B50000"],
        radar: {
          indicator: this.echartsData.indicator, //指示器名称
          shape: 'circle', //原型是六边形，加了该字段为圆形
          splitNumber: 4, //里面有几个圆
          axisName: { //指示器样式
          color: '#004C82', //指示器的文字颜色
          lineHeight:20,//指示器行高
          borderRadius:5,//指示器圆角
          padding:[0,3,0,3],//指示器的内边距
          backgroundColor:'#fff'//指示器的背景颜色
          },
          splitLine:{ //里面四个圈线条样式
            lineStyle: {
              color: ['rgba(255, 255,255, 0.4)', 'rgba(255, 255,255, 0.4)', 'rgba(255, 255,255, 0.4)', 'rgba(255, 255,255, 0.4)'],//分别对应四个第一个对应最里面的圈
            }  
            // show : false
            
          },

                      lineStyle:{
                        color: "rgba(255, 255,255, 0.4)",//射线的颜色
                      },
                    },
          splitArea: { //四个圈的分隔区域样式
                      areaStyle: {

                        shadowColor: 'rgba(0, 0, 0, 0.2)',//分割区域阴影
                        shadowBlur: 10
                      }
                    },
          },
          
        series: [
          {
            type: "radar",
            data: [
              {
                value: this.echartsData.value,
                areaStyle: {
                  color: new echarts.graphic.RadialGradient(0.1, 0.6, 1, [
                    {
                      color: "#B50000",
                      offset: 0
                    },
                    {
                      color: "rgba(255, 145, 124, 0.9)",
                      offset: 1
                    }
                  ])
                }
              }
            ],
            lineStyle: {
              width: 1,
              opacity: 0.5
            },
            symbolSize: 1
          }
        ]
      };
      option && mychart.setOption(option);

代码里面都有注释，可以复制到自己的代码中进行样式调试

最常用的样式修改也就是线的修改，splitLine：分割线修改样式的属性，axisLine：射线修改样式的属性，splitArea：分割区域的样式，lineStyle：带有数的线样式修改

注意：我的图表内的指示器标题，以及value数据都是对象引入的，大家用的时候注意一下
