我想创建这个图表。我知道，我应该提供类似 MWE 的东西，但我不知道从哪里开始。我查看了 pgfplots 手册中的所有示例，但我没有看到任何可以作为这个图表的起点的图表。这可能吗？你能帮我创建它吗？谢谢！
答案1
在现有的解决方案中，我发现最接近您的屏幕截图的解决方案可能是这个答案。这里有一个方法有些相似的版本，但使用的是图片而不是宏。我发布它的原因是这个版本可以轻松转换（线宽也会转换，这就是为什么有这个神秘的\pgfgettransformentries...）。所以你只需要说
\path (0,0) pic[scale=5,donut/offset=90]{donut=26};
要得到
以下是包含此示例和其他示例的代码。我尝试包含几个选项。最近添加的选项是clockwise和bar（针对 Stefan Pinnow）。`bar 选项的实现有点“麻烦”，因为我不想只画一条白线，如果背景不平凡，或者有人想调整不透明度，这会适得其反。
