目前，我对在互联网上找到的蜘蛛网解决方案感到非常高兴。不幸的是，我发现了两个问题：
- 图表从 3 点开始
- 方向为逆时针
我花了很长时间尝试自己修复它（并使用了搜索功能），但无法修复它。有人能帮我吗，告诉我现有编码的哪些部分需要更改
- 12点开始
- 设置顺时针方向
那太棒了 :-) 提前谢谢大家。这里是 MWE：

:Title: Spiderweb diagram
Such a diagram defines a set of dimensions D = {D1,...,Dn} and a common scale unit
range from 0 to a maximal value U. Each individual sample contains a sequence of
pairs (Dx,Vx) with 0 <= Vx <= U for all Dx in D.
The diagram is rendered as a spiderweb, where the D dimension axes meet each
other in the origin in an angle of 360/D and are each divided in U units. Each
sample is rendered as half-opaque colored path along the particular value unit nodes
on each dimension. Overlapping parts will be rendered in a composite color.

答案1
像这样吗？更新：犯了愚蠢的错误，抱歉。编辑：我所做的只是查找\X变量，反转它们的符号（顺时针与逆时针），并将整个变量移动 90 度。最初，我把下午 3 点误读为 30 度，因此引入了不必要的\X-1 偏移。我还将各个参数移动了\path (-n*\A+90:\L) node (Ln) {\tiny ...};90 度，并引入了 - 符号。
