如何使用 pgfgantt 绘制多处理器甘特图？

我有一个关于普格夫甘特包裹：

对于一篇论文，我需要能够绘制这样的图表：

但是，根据我目前看到的说明pgfgantt，我似乎无法弄清楚如何操作。到目前为止，我只设法得到了类似这样的结果：

在此处输入图片描述

这是我的代码：

\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}

所以我的问题是：如何在多个处理器（P_x）上执行任务并使它们看起来像是属于一起（删除黑色边框，只有一个符号等）？

希望您不介意我提出一个替代方案。如果您已经熟悉该pgfplots软件包，那么使用此软件包代替pgfgantt可能是一个简单的选择，而不必对pgfgantt代码进行太多调整。

area plot这是使用手册第 4.5.10 节中描述的示例pgflots。

按以下顺序指定\addplot坐标：{(south west) (north west) (north east) (south east)}

环境的一般设置axis有所增加（我感觉通常会发生这种情况pgfplots）。如果您对特定设置有任何疑问，我很乐意在评论中回答。

结果：

新甘特图

代码：

\usepackage{pgfplots}
\usetikzlibrary{intersections}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
