echarts饼图图例重叠

在Echarts饼图中，可以通过设置series中的avoidLabelOverlap属性来控制是否启用防止标签重叠策略。当avoidLabelOverlap设置为true时，如果标签拥挤重叠，系统会自动挪动各个标签的位置，以防止标签间的重叠。而当avoidLabelOverlap设置为false时，标签可能会重叠在一起，导致图例不清晰。因此，如果希望避免图例重叠，可以将avoidLabelOverlap设置为true。例如，在Echarts饼图的配置代码中，可以将avoidLabelOverlap属性设置为true，如下所示：

series: [
  {
    name: "危险源状态",
    type: "pie",
    radius: ["25%", "45%"],
    center: ["50%", "60%"],
    avoidLabelOverlap: true, // 设置为true以避免标签重叠
    label: {
      normal: {
        show: true,
        position: "center"
      },
      emphasis: {
        show: true,
        textStyle: {
          fontSize: "12",
          fontWeight: "bold"
        }
      }
    },
    labelLine: {
      normal: {
        show: true
      }
    },
    data: pieData
  }
]

通过将avoidLabelOverlap设置为true，可以确保饼图的图例不会重叠，从而提高图表的可读性。<span class="em">1</span><span class="em">2</span>
