条形图 - 单独更改每个条形的表面颜色

我正在使用Matlab命令bar来创建条形图。我正在使用它matlab2tikz来转换它。我想将每个条形的表面颜色分别更改为我选择的 rgb 颜色。Matlab我可以使用此代码来实现这一点：

b = bar(x,y,'FaceColor','flat') b.CData(2,:) = [1 0 0]; b.CData(3,:) = [0 1 0]; b.CData(4,:) = [0 0 1]; b.CData(5,:) = [0 0 0]; b.CData(6,:) = [1 0 1];

然而，这会导致我的 所有条都透明texfile，如下所示：

下面这行代码用来创建条形图：

\addplot[ybar, bar width=0.8, fill=mycolor1, draw=black, area legend] table[row sep=crcr] {%

使用最上面一行的 mycolor1：

\definecolor{mycolor1}{rgb}{0.00000,0.44700,0.74100}%

这给出了以下结果：

我想调整 texfile，以便获得我想要的脸部颜色。这可以通过使用不同的 Matlab 代码或通过 Matlab 调整 texfile 来实现，如下所示：

    matlab2tikz('Uebersicht_Nadelauszugskraefte.tikz',...
        'extraaxisoptions',['legend style={legend columns=5},',...
        'legend style={font=\tiny},'])

非常感谢你的帮助！

直接使用 TikZ (而不是mathlab2tikz) 怎么样？

在此处输入图片描述

\documentclass[tikz,border=5mm]{standalone}
\begin{document}
\begin{tikzpicture}[y=.5mm,x=1.5cm]
\draw[gray!50,local bounding box=L] (0,0) grid[xstep=1.5cm,ystep=20] (7,160);
\foreach \i/\ione/\itwo/\itext in
{1/0/0/,
2/49.2731776918684/19.964130020244/t=3.0,
3/55.5745267232259/15.9911247772533/t=3.5,
4/60.3699144999186/7.89742116804573/t=4.0,
5/91.1499318440755/13.3824237377185/t=4.5,
6/150.601191206667/2.13783749065102/t\approx 30
}{
\draw[blue!50,line width=10mm] 
(\i,0) node[below=-5mm,black]{$\itext$}--+(90:\ione) coordinate (tmp);
\draw[red,line width=10mm] (tmp)--+(90:\itwo);
}
\foreach \i in {0,...,8}{
\pgfmathsetmacro{\j}{int(20*\i)}    
\path (0,\j) node[left]{$\j$};
}

\draw (0,0) rectangle (7,160);
\path
(L.west)+(180:1) node[rotate=90]{Kan\"ulenauszugskraft in $N$}
(L.south)+(-90:18) node{Messreihennummer}
;

% legends (as a matrix node)
\path (2,130) node[matrix,draw,fill=white]{
\draw[line width=2mm,blue!50] (0,0)--+(0:.5);&\node{Probe 1};\\
\draw[line width=2mm,red] (0,0)--+(0:.5);&\node{Probe 2};\\
};
\end{tikzpicture}
\end{document}
