pgfplots 中带有误差线的极轴

pgfplots 中带有误差线的极轴

我尝试在极坐标中绘制一些带有误差线的值。这是我的 MWE

\begin{tikzpicture}
  \begin{polaraxis}
    \addplot+[only marks,mark size=1.5pt,error bars/.cd,y dir=both,y explicit] coordinates {(1,0.5)+-(0,0.1) (20,0.7)+-(0,0.1)};
  \end{polaraxis}
\end{tikzpicture}

结果是

在此处输入图片描述

但误差线应在径向。

答案1

这是一个古老的话题，但几天前我问了自己同样的问题，因为我需要一个圆形图。我在误差线方面遇到了同样的问题，但我找到了一个可行的替代解决方案，它在这里：我在要绘制“置​​信区间”的轴上添加了 2 点线。

看起来像这样：
