在 tikz 中对齐嵌套的甜甜圈形状的图表

Question

我认为你正在寻找这样的东西：

为了实现这一点，我修改了\innerchartthreed宏，现在它采用逗号分隔的四元组列表：数量、颜色、名称、偏移量。OP 中的数量加起来为 360，但实际上，代码会将适当的角度计算为这些数量总和的百分比，因此您可以使用原始数据来指定数量。

接下来，我更改了\innerchartthreed宏，使其将名称添加到圆圈外部，并在每个段内添加一条线来标记。由于图片中的圆圈实际上是椭圆形，我看不出有什么简单的方法可以自动设置名称与中心的距离，因为与图表中心的距离会随着角度而变化，因此我添加了偏移量以将标签沿径向线进一步向外移动。此外，我添加了一个可选参数来\innerchartthreed设置内圆相对于外圆盘的起始角度。这允许您调整内圆以匹配外圆（奇怪的是，调整应该是 228，但我发现 222 看起来更好）。

最终结果是，带有标签的内盘由以下方式绘制：

  \innerchartthreed[222]{% amount/colour/name/label offset
      95/cardinal!95/Cardiomyocyte/1.2,
      38/cardinal!60/Fibroblast/0.2,
      38/cardinal!50/HEK-293/0,
      38/cardinal!40/SH-SY5Y/0.5,
      19/cardinal!40/RBL-1/0.5,
      56/green!90/Cortex/1,
      38/green!70/Hippocampus/1.8,
      19/green!50/Ventricular/1.8,
      19/green!50/DRG/1.5
    }

之后，我又做了一些类似的调整，以便 \piechartthreed放置外圆标签。带标签的外圆盘不是由以下人员绘制的：

  % amount/color/name
  \piechartthreed[scale=0.8, background color=orange!50, mix color=darkgray]{
      228/red/Non-neuronal\\72.3\%,
      132/green/Neuronal\\45.5\%
  }

当然，我只是破解了问题中的代码，正如 OP 所说，大部分艰苦的工作都是由 Alain Matthes 在他的精彩回答中完成的如何使用 pgf-plot 设计 3D 甜甜圈饼图？。

哦，楼主SH-SY5输入了两次标签，所以我删除了一个。不确定 72.3% 和 45.5%，但我没有更改这个。

以下是更新后的代码：
