我能够根据以下答案创建饼图如何绘制条形图和饼图。
我意识到我的文档是以灰度打印的，并且了解了图案（pgfplots 的模式列表库在哪里？)，可以应用于绘图对象。在条形图中，我可以轻松提供一个\addplot基于我之前的问题的为 tikzpicture 垂直条添加背景图案。
如何使用饼图来实现这一点，使每个切片都有独特的图案背景？
这是我使用平面颜色的代码：

答案1
您确定要这样做吗？我认为，使用模式会产生“过于拥挤”的结果。
新的样式slice type pattern允许您指定图案，方式与您使用 指定填充颜色的方式类似slice type。

前面的回复回答了这个问题，但为了使％数字可见，您可以使用节点命令的填充键。
\begin{pgfonlayer}{foreground}
\path \c -- node[fill=white,pos=\d,pie values,values of \s]{$\v\%$} +(\midA:\r);
\end{pgfonlayer}
