如何避免 pgfgantt 中笨拙的 \ganttlink？

我想在此图表（Microsoft Project 软件）中清晰显示甘特图，尤其是与活动 A 链接的活动 B、C 和 D。请帮助我。

    \documentclass[12pt,border=12pt]{standalone}
    \usepackage{tikz,pgf,pgfgantt}
    \usepackage[utf8]{inputenc}
    \usepackage{xcolor} 

    \begin{document}
    \begin{ganttchart}[vgrid, hgrid, bar/.append style={orange}, link/.append style={thick}, link bulge=.5, link/.style={->, thick}]{1}{33}
   \gantttitle{Example 1 - Gantt Chart (in Days)}{33} \\
   \gantttitlelist{1,...,33}{1} \\
   \ganttgroup{Project Duration}{1}{33} \\
   \ganttbar{Activity A}{1}{2} \\
   \ganttbar{Activity B}{3}{6} \\
   \ganttbar{Activity C}{3}{5} \\
   \ganttbar{Activity D}{3}{7} \\
   \ganttbar{Activity E}{7}{8} \\
   \ganttbar{Activity F}{8}{11} \\
   \ganttbar{Activity G}{7}{9} \\

答案1

您可以尝试使用链接的link bulge和参数。定义链接的水平延伸，而定义链接折回的两个条之间的分数垂直距离。例如，link midlink bulgelink mid

\ganttlink[link bulge=0.4]{elem1}{elem2}
\ganttlink[link bulge=1, link mid=0.3]{elem1}{elem3}
\ganttlink[link bulge=1.3]{elem1}{elem4}

你得到
