echarts饼图线条显示百分比

要在echarts饼图中显示线条百分比，你可以使用formatter属性来实现。在series中的label属性下，设置formatter属性的值为"{c}"。这样，每个扇形区域的标签文本就会显示对应的百分比值。例如，你可以在series中的label属性中添加以下代码来实现：

label: {
normal: {
show: true,
textStyle: {
fontSize: 22
},
formatter: "{c}"
}
}

这样，饼图中的每个扇形区域上都会显示对应的百分比值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
