我很高兴看到解决方案饼图标签，但我不知道如何将图例放在饼图的右侧。为此，我喜欢这个想法带合并图例位置的饼图- 在我的版本中添加一个style={legend to the east}。但我不知道如何将其编辑到这个 MWE 中。
那么，问题是：我该如何利用这段代码
\tikzset{
legend to the south/.code={
\coordinate[xshift=-1.5cm,
yshift=(\value{pgfpie@sliceLength}*0.5+1)*0.5cm-4em] (legendpos) at
(current bounding box.south);},
}
将以下 MWE 的图例放在东边？

切勿修复正在运行的代码。
我只改变了移位参数来得到
