调整 tkzKiviatDiagram 图表轴标签大小

Question

我试图在一张 A4 纸上显示多个 Kivat 图表。因此，我将它们嵌入到一个图下的子图中。这就是我重新缩放 Kivat 图表以适合一页的原因。但是，我注意到虽然所有组件都缩小了，但轴标签却没有缩小，而是保持固定的字体大小。以下是我的代码：

\begin{figure}[t!] % "[t!]" placement specifier just for this example
    \begin{subfigure}{0.48\textwidth}
\begin{tikzpicture}
\tkzKiviatDiagramFromFile[
        scale=.22,
        label distance=.6cm,
        gap  = 1,label space=4, size = 3,  
        lattice = 10]{tableau.dat}

\tkzKiviatLineFromFile[thick,
                       color      = blue,
                       mark       = ball,
                       ball color = blue,
                       mark size  = 4pt,
                       fill       = blue!20]{tableau.dat}{2}
\tkzKiviatLineFromFile[thick,
                       color      = red,
                       mark       = ball,
                       ball color = red,
                       mark size  = 4pt,
                       fill       = red!20]{tableau.dat}{1} 
\tkzKiviatLineFromFile[thick,
                       color      = green,
                       mark       = ball,
                       ball color = green,
                       mark size  = 4pt,
                       fill       =  green!20]{tableau.dat}{3} 
\tkzKiviatLineFromFile[thick,
                       color      = orange,
                       mark       = ball,
                       ball color = orange,
                       mark size  = 4pt,
                       fill       =  orange!20]{tableau.dat}{4} 
\tkzKiviatLineFromFile[thick,
                       color      = pink,
                       mark       = ball,
                       ball color = pink,
                       mark size  = 4pt,
                       fill       =  pink!20]{tableau.dat}{5} 
\end{tikzpicture}
\caption{First subfigure} \label{fig:a}
\end{subfigure}\hspace*{\fill}
\end{figure}

结果如下：

有没有办法可以减小 7 个轴标签的尺寸（通知、激励发展依从性......）
