\pgfplotstable@loc@TMPa 定义中的参数编号非法。尝试使用 tikz 和 pgfplots 绘图

但是我得到了错误：Illegal parameter number in definition of \pgfplotstable@loc@TMPa 我花了很长时间试图找出错误，但我找不到。有谁能发现我的错误？我也对这个错误感到很困惑，因为 csv 是有效的。

Answer 1

这些#字符在 TeX 中很特殊，它们表示参数。使绘图正常工作的一种方法是从表中删除它们（因为这里不使用它们）。也许更优雅的可能性是使用键text special chars。

或者您也可以使用ignore chars，请参阅pgfplotstable第 7 页的手册 v1.16：

然后你需要更换

\addplot table [x=iteration, y=iteration, col sep=comma,text special chars={\#}] {hdfs_logs.csv};

经过

\addplot table [x=iteration, y=iteration, col sep=comma, ignore chars={\#}] {hdfs_logs.csv};

在当前的例子中，这没有任何区别，因为没有使用相应的列。
