从 pgfgantt 甘特图中删除未使用的行

我正在使用 pgfgrantt 包在 Overleaf 中准备甘特图。我使用条形图和里程碑顶部移位选项将它们向上移动并挤压得更近。然而，这会在图表底部留下很多未使用的行，如附图所示。我该如何摆脱这些行？下面的代码可以重现所附的图表。在此处输入图片描述

\begin{ganttchart}[
    vgrid,
    hgrid,
   milestone top shift=-2.45,
    milestone right shift=0.3,
    group top shift = -0.05,
    bar height = 0.2,bar label node/.append style={align=right}
    ]{1}{24}
  \gantttitle{2022}{3}   \gantttitle{2023}{12} 
  \gantttitle{2024}{9} \\
  \gantttitlelist{10,11,12}{1}  \gantttitlelist{1,...,12}{1} \gantttitlelist{1,...,9}{1}\\
  \ganttgroup{a}{1}{11.5} \\
  \ganttbar[bar top shift=-0.6]{b}{1}{2.5}{jj} \\
  \ganttlinkedbar[bar height=0.2, bar top shift=-1.2]{c}{3.5}{8.5} \\
  \ganttlinkedbar[bar top shift=-1.8]{d}{8.5}{10.5} \\
  \ganttlinkedmilestone{e}{11} 
  %%
  \ganttgroup[group top shift = -1.6]{2\\f}{7}{15} \\
  \ganttbar[bar height = 0.4, bar top shift=-2.1]{g \\[-3pt]h}{7}{8}{jj} \\
  \ganttlinkedbar[bar height=0.4, bar top shift=-2.2]{i \\[-3pt] j}{9}{11} \\
  \ganttlinkedbar[bar height = 0.4, bar top shift=-2.3]{k \\[-3pt] l}{12}{14} \\
  \ganttlinkedmilestone[milestone top shift = -2.6]{m}{15}
  %%
  \ganttgroup[group top shift = -1.6]{n}{3}{23} \\
  \ganttbar[bar height = 0.2, bar top shift=-2.1]{p}{3}{5}{jj} \\
  \ganttlinkedmilestone[milestone top shift = -2.7]{o}{6} \\
  \ganttlinkedbar[bar height=0.2, bar top shift=-3.1]{q}{15}{18} \\
  \ganttlinkedbar[bar height = 0.4, bar top shift=-3.5]{r \\[-3pt] s}{19}{22} \\
  \ganttlinkedmilestone[milestone top shift = -3.8]{t}{23}
\end{ganttchart}

图表的高度是通过将\ganttbar、\ganttgroup、 ... 命令的数量乘以固定长度 而自动计算出来y unit chart的。因此，即使您通过手动移动某些行来挤压它们，图表的高度也不会受到影响。我建议将其设置y unit chart为较小的值，并且不要手动移动条形图。

\begin{ganttchart}[..., y unit chart = 7mm, ...]

其他问题：您不应该使用\\来断开标签中的线条，但是\ganttalignnewline。（或者，您可以将其设置newline shortcut为 false，但随后必须使用\ganttnewline来分隔图表中的线条）。

\ganttbar{g \ganttalignnewline[-3pt]h}{7}{8}{jj}

最后，换行符似乎在标签中无论如何都不起作用\ganttgroup。如果您确实需要两行，请将标签排版为\savebox。

\newsavebox\twof
\savebox\twof{\bfseries\begin{tabular}{@{}r@{}}2\\[-3pt]f\end{tabular}}
...
\ganttgroup{\usebox\twof}{7}{15}
