我试图将这三个饼图并排对齐，并为这三个饼图使用相同的图例，但每个饼图都有一个标题。但我所做的更改没有奏效。这是我的代码：

答案2
这轮图我写的包，可以使用。
首先，使用包将数据存储在列表中\WCdata，将颜色存储在列表中\WCcolors物品清单。
定义一个命令\WCtest，其输出取决于百分比是否大于 3。此命令用于键data和wheel data。此处，使用 来获取百分比\WCperc。
使用 键wheel data pos={\WCpercentage<10?0.85:0.6}，若百分比小于10，则车轮数据的位置为0.85，否则为0.6。
第一个\wheelchart使用键定位at={(-7,0)}。第二个使用初始坐标定位(0,0)，第三个使用键定位at={(7,0)}。
第一个变量对应于值，第二个变量对应于列表\WCdata和的项目编号\WCcolors。例如，第一个\wheelchart有值31和69，项目编号为2和5。
图例放置在单独的 中\wheelchart。我们在这里设置键data=、slices style={fill=none}和wheel data={}，这样就不会绘制任何切片，也不会放置任何数据或车轮数据。
图例由键决定legend。这是一个tabular放置在 中的\node。行由键决定legend row。可以使用 获得所有行的结果\WClegend。
