echarts柱状图只有一组数据显示图例

根据引用\[1\]和引用\[2\]的内容，你可以通过设置`series`中的`name`属性来显示图例。在你的代码中，每个柱状图都有一个`name`属性，分别是"峰"、"平"和"谷"。这些名称将被用作图例的标签。确保在Echarts的配置中设置`legend`属性为`show: true`，以确保图例显示出来。

以下是一个示例代码片段，展示了如何设置图例：

option = {
  legend: {
    show: true
  },
  series: \[
    {
      name: "峰",
      type: "bar",
      stack: "值",
      data: fengList,
      itemStyle: {
        color: state.getThemeConfig.curveConfig\[0\],
      },
    },
    {
      name: "平",
      type: "bar",
      stack: "值",
      data: pingList,
      itemStyle: {
        color: state.getThemeConfig.curveConfig\[1\],
      },
    },
    {
      name: "谷",
      type: "bar",
      stack: "值",
      data: guList,
      itemStyle: {
        color: state.getThemeConfig.curveConfig\[2\],
      },
    },
  \],
};

通过以上配置，你的柱状图将会显示具有相应名称的图例。
