echart 图表 柱状图设置圆角，图例设置为圆形，图例距离

效果：

设置圆角：
圆角：
borderWidth：宽度

itemStyle: {
              normal: {
                //这里设置柱形图圆角 [左上角，右上角，右下角，左下角]
                barBorderRadius: [10, 10, 0, 0],
              },
            },

图例形状圆形：
icon: “circle”, // 这个字段控制形状 类型包括 circle 圆形，triangle 三角形，diamond 四边形，arrow 变异三角形，none 无

legend: {
          icon: "circle",
          padding: [20, 15, 0, 0], //设置图例距上⽅距离，距右⽅距离，距下⽅距离，距左⽅距
          x: "right", //居右显示
          textStyle: {
            // 图例文字的样式
            color: "#fff",
            fontSize: 12,
          },
        },
