尝试制作自动直方图（在 pgfplots 中？）

Question

如何将宏生成的自动表格转换为自动直方图？最好的方法是使用 吗pgfplots？

我尝试过这种方法但出现了一些错误：

...

\usepackage{pgfplots}

\pgfplotsset{%
            /pgf/number format/use comma,%
            compat=newest}

... 

\begin{figure}
\centering
  \begin{tikzpicture}
    \begin{axis}
    \addplot coordinates{%
                        (\textvisiblespace,1)
                        \tl_use:N \l_aw_tab_rows_tl%
                        };
    \end{axis}
  \end{tikzpicture}
\caption{histogram.}
\end{figure}

...

\cs_new:Npn \aw_generate_row:n #1
    {
