问题

可以看出，28°标签没有印在绿色楔形物的“顶部”。 （当然，其他标签也是如此。）

如何确保标签始终打印在“顶部”？

答案1

只需修改一些参数：

添加：在 的定义中使用值 5.3 作为 的第一个参数\uput（代替 2）\andelB，您将获得大圆圈外的标签。（在这种情况下，不要忘记删除\textcolor{white}黑色区域）：

答案2

的强制参数\uput{<distance>}定义了放置内容的位置与相关点之间的距离。您在宏8pt中使用\andelB...将其增加到更大的值，例如25pt：

\def\andelB[#1]#2#3#4{%
  \pswedge[fillstyle = solid, fillcolor = #1]%
     {\radius}{\fpeval{round(#2/\eleverTotal*360,9)}}{\fpeval{round(#3/\eleverTotal*360,9)}}
  \ifstrequal{#1}{black}%
    {\psarc[linecolor = white]%
       (0,0){0.5}{\fpeval{round(#2/\eleverTotal*360,9)}}{\fpeval{round(#3/\eleverTotal*360,9)}}
     \uput{25pt}[\fpeval{round((#2+#3)/\eleverTotal*180,9)}]%
       (0,0){\textcolor{white}{\footnotesize\SI{\fpeval{round((#3-#2)/\eleverTotal*360)}}{\degree}}}}
    {\psarc%
       (0,0){0.5}{\fpeval{round(#2/\eleverTotal*360,9)}}{\fpeval{round(#3/\eleverTotal*360,9)}}
     \uput{25pt}[\fpeval{round((#2+#3)/\eleverTotal*180,9)}]%
       (0,0){\footnotesize\SI{\fpeval{round((#3-#2)/\eleverTotal*360)}}{\degree}}}%
}

答案3

\psset{
  unit = 0.4,opacity=0.5,
  linejoin = 1
}

但是，你可以愚弄\psChart宏来完成所有的计算：

\documentclass{beamer}
\usepackage{pstricks-add}
\newcounter{temp}
\def\Chart{\psChart{55,28,69,97,69,42}{}{4}}
\begin{document}

\begin{frame}{Opgave~$7$}
\begin{center}
\begin{pspicture}(-3,-3)(3,3)

  \rput(psChartI1){55}}
\visible<2->{%

  \rput(psChartI1){55}\rput(psChartI2){28}}

  \rput(psChartI1){55}\rput(psChartI2){28}\rput(psChartI3){69}}
\visible<4->{%
  \setcounter{temp}{0}%
  \psset{userColor={yellow!70,red!70,green!80,orange!80,white,white}}\Chart
  \psforeach{\iA}{55,28,69,97}{\stepcounter{temp}\rput(psChartI\thetemp){\iA}}}
\visible<5->{%
  \setcounter{temp}{0}%
  \psset{userColor={yellow!70,red!70,green!80,orange!80,blue!70!white,white}}\Chart
  \psforeach{\iA}{55,28,69,97,69}{\stepcounter{temp}\rput(psChartI\thetemp){\iA}}}
\visible<6>{%
  \setcounter{temp}{0}%
  \psset{userColor={yellow!70,red!70,green!80,orange!80,blue!70!white,black}}\Chart
  \psforeach{\iA}{55,28,69,97,69}{\stepcounter{temp}\rput(psChartI\thetemp){\iA}}
  \rput(psChartI6){\color{white}42}}
\pscircle{4}
\degrees[26]\multido{\iA=0+1}{26}{\psline(4;\iA)(4.1;\iA)}
\end{pspicture}
\end{center}

答案4

只是为了好玩：一个 Ti钾Z 替代方案。您只需指定数字和颜色列表，

\def\LstNums{4,2,5,7,5,3}
\def\LstColors{"yellow!70","red!70","green!80","orange!80","blue!70!white","black"}

代码将完成剩下的工作。根据 RGB 颜色模型，选择与填充颜色互补的标签颜色。（其他颜色模型看起来可能更好/不同。）这样标签和内弧就可见了。动画从幻灯片 4（\def\istart{4}）开始，如您的代码所示。

如果将标签移近中心，它们将不会被楔子覆盖，因为楔子是在图层上绘制的background。

这里我使用了cmy颜色模型。当然，很有可能有比 更好的映射x\mapsto 1-x。x\in\{c,m,y\}但在我看来，结果的可读性很好。
