![x 坐标中的逗号(间隔)](https://linux22.com/image/433961/x%20%E5%9D%90%E6%A0%87%E4%B8%AD%E7%9A%84%E9%80%97%E5%8F%B7%EF%BC%88%E9%97%B4%E9%9A%94%EF%BC%89.png)
我怎样才能将 x 坐标中的点替换为逗号?

ylabel={Nálet [h]},

enlarge x limits=0.15,
symbolic x coords={$(-\infty.25)$, $\langle25.30)$, $\langle30.35)$, $\langle35.40)$, $\langle40.45)$, $\langle45.50)$, $\langle50.\infty)$},
xtick=data, bar width=30pt,nodes near coords,

\addplot table {\data};
\end{axis}

谢谢

这非常类似于Pgfplots:数据表中的标签未按预期工作这个想法是使用行索引而不是符号 x 坐标按顺序绘制行,并使用第二列的 y 值,如下所示:
\addplot table[x expr=\coordindex,y index=1] {\data};
对于刻度标签,使用第一列:
xticklabels from table={\data}{0},
现在您只需指定一次标签,并且可以使用逗号而不会出现有关符号坐标的错误。
