如何使用 pgfgantt 繪製多處理器甘特圖？

我有一個關於甘特包裹：

對於一篇論文，我需要能夠繪製這樣的圖表：

在此輸入影像描述

然而，根據我迄今為止所看到的說明pgfgantt，我似乎不知道該怎麼做。到目前為止，我只得到了這樣的東西：

在此輸入影像描述

這是我的程式碼：

\begin{ganttchart}[
inline, % puts the label inside the bar
hgrid,
vgrid,
bar height=1
]{1}{10}
% P3
\ganttgroup[inline=false,group/.style={draw=none, fill=none}]{P3}{2,0}{25,0}
\ganttbar[bar/.append style={fill=green}]{$T1$}{1}{2} 
\ganttbar{}{3}{4} 
\ganttbar[bar/.append style={fill=orange}]{$T3$}{5}{7}
\ganttbar{}{8}{9} 
\ganttbar[bar/.append style={fill=cyan}]{$T5$}{10}{10} 
\\
% P2
\ganttgroup[inline=false,group/.style={draw=none, fill=none}]{P2}{2,0}{25,0}
\ganttbar[bar/.append style={fill=green}]{$T1$}{1}{2} 
\ganttbar{}{3}{4} 
\ganttbar{}{3}{4} 
\ganttbar{}{5}{7}
\ganttbar[bar/.append style={fill=yellow}]{$T4$}{8}{9}
\ganttbar[bar/.append style={fill=cyan}]{$T5$}{10}{10} 
\\
% P1
\ganttgroup[inline=false,group/.style={draw=none, fill=none}]{P1}{2,0}{25,0}
\ganttbar{}{1}{4} 
\ganttbar[bar/.append style={fill=orange}]{$T3$}{5}{7}
\ganttbar[bar/.append style={fill=yellow}]{$T4$}{8}{9}
\ganttbar{}{10}{10}
%
\end{ganttchart}

所以我的問題是：如何在多個處理器（P_x）上執行任務並使其看起來像是屬於在一起（刪除黑色邊框，僅一種符號等）？

答案1

我希望你不介意我提出一個替代方案。如果您已經熟悉該pgfplots包，那麼使用該套件pgfgantt可能是一個簡單的選擇，而不必過多地處理pgfgantt程式碼。

area plot這是使用手冊第 4.5.10 節中所述的範例pgflots。

按以下順序指定\addplot座標：{(south west) (north west) (north east) (south east)}

環境的整體設定axis已經增長了一點（我覺得通常會發生這種情況pgfplots）。如果您對具體設定有任何疑問，我很樂意在評論中回答。

結果：

新甘特圖

代碼：
