未链接的甘特图组

Question

我创建了一个甘特图，其中包含一些甘特图组，用于指示各个阶段。但是这些甘特图组与我不想要的任务相关联（例如第一个图，我希望它像红色箭头一样）。

我尝试将之前的对象与甘特图组之后的对象链接起来，但是没有成功（就像第二张图我尝试将对象 3 与对象 5 链接起来一样）。

有什么解决办法吗？！

您必须尝试使用​​链接的参数，即link bulge和link mid。它们允许您指定垂直链接的凸起和位置。pgfgantt有关更多信息，请参阅文档，第 38 页。

无论如何，代码：

\documentclass{article}
\usepackage{pgfgantt}
\begin{document}
       \begin{ganttchart}[
    vgrid
    ]{0}{17}
    \gantttitle{Weeks}{18} \\
    \gantttitlecalendar*[title left shift=1,title right shift=1]{1}{16}{day}
     \\[grid]

    \ganttgroup{Phase 1}{1}{5} \\
    \ganttbar{System Analysis}{1}{3} \\
    \ganttlinkedbar{System Design}{4}{5} \ganttnewline
    \ganttmilestone{System Architecture}{5} \ganttnewline

    \ganttgroup{Phase 3}{6}{12} \\
    \ganttbar{System Implementation}{6}{8} \ganttnewline
    \ganttlinkedbar{Benchmarks Implementation}{9}{12} \ganttnewline
    \ganttmilestone{System and Benchmarks code}{12} \ganttnewline

    \ganttgroup{Phase 4}{13}{13} \\
    \ganttbar{System Evaluation}{13}{13} \ganttnewline
    \ganttmilestone{Evaluation Results}{13} \ganttnewline

    \ganttgroup{Phase 4}{13}{16} \\
    \ganttbar{Documentation}{13}{16}\ganttnewline
    \ganttmilestone{Milestone}{16} 

    \ganttlink{elem1}{elem2}
    \ganttlink{elem2}{elem3}
    \ganttlink[link bulge=1,link mid=0.3]{elem3}{elem5}
    \ganttlink{elem5}{elem6}
    \ganttlink{elem6}{elem7}

    \ganttlink[link bulge=1,link mid=0.3]{elem7}{elem9}
    \ganttlink{elem9}{elem10}

    \ganttlink[link bulge=1,link mid=0.3]{elem10}{elem12}
    \ganttlink{elem12}{elem13}

    \end{ganttchart}\end{document}

编辑

由于用户在评论中完善了他的请求，因此我在此报告了新代码。为了使组的第一个项目不链接到组本身，只需将 替换为 即可\ganttlinkedbar。\ganttbar我在以下行中完成了此操作：

 \ganttbar{System Implementation}{6}{8} \ganttnewline

新代码：

    \documentclass{article}
\usepackage{pgfgantt}
\begin{document}
\begin{ganttchart}[
vgrid
]{0}{17}
\gantttitle{Weeks}{18} \\
