echarts 柱形图百分数数据

要在echarts柱形图中显示百分数数据，你可以使用label的formatter属性进行设置。你可以在关键代码中找到如下部分：

label: {
   normal: {
      show: true,
      position: "top",
      color: "#000",
      fontSize: 20,
      formatter: "{c}%"
   },
},

其中formatter属性中的"{c}%"表示将数据以百分数形式显示在柱形图上。这样设置后，柱形图上的数据将以百分数形式显示。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
