如何在雷达图中添加两行 \rput

Question

我能够使用下面提到的代码绘制雷达图：

\begin{center}
\begin{pspicture}(-4,-4)(4,4)
\psset{unit=1.2}
\degrees[270]
\psaxes[labels=none,axesstyle=polar,ticklinestyle=dashed,tickcolor=black!40](0,0)(-4,-4)(4,4)
\psaxes[dx=1,dy=1,Dx=25,Dy=25](0,0)(0,0)(4,4)%
\degrees[360]
\psxTick{0}(-1){25}
\psxTick{0}(-2){50}
\psxTick{0}(-3){75}
\psxTick{0}(-4){100}
\psyTick{0}(-1){25}
\psyTick{0}(-2){50}
\psyTick{0}(-3){75}
\psyTick{0}(-4){100}
\psset{fillstyle=solid,opacity=0.5}
\pswedge[fillcolor=black!10]{\pskilla}{0}{40}
\pswedge[fillcolor=black!50]{\pskillb}{40}{80}
\pswedge[fillcolor=black!90]{\pskillc}{80}{120}
\pswedge[fillcolor=black!10]{\pskilld}{120}{160}
\pswedge[fillcolor=black!50]{\pskille}{160}{200}
\pswedge[fillcolor=black!90]{\pskillf}{200}{240}
\pswedge[fillcolor=black!10]{\pskillg}{240}{280}
\pswedge[fillcolor=black!50]{\pskilli}{280}{320}
\pswedge[fillcolor=black!90]{\pskillj}{320}{360}
\rput(4.9;20){Skill 1 }
\rput(4.9;60){Skill 2}
\rput(4.9;100){Skill 3}
\rput(4.9;140){Skill 4}
\rput(4.9;180){Skill 5}
\rput(4.9;220){Skill 6}
\rput(4.9;260){Skill 7}
\rput(4.9;300){Skill 9}
\rput(4.9;340){Skill 10}
\psset{opacity=1}
\end{pspicture}
\end{center}

此图表需要修改，添加如下文字： 每项技能后；希望在其下方显示百分比。请提出建议。
