我想xlabel在分组条形图上添加第二个TiKz添加第二个，但似乎无法解决。所以我找到了这个cm 超级字体包裹：http://ctan.org/pkg/cm-super。或者我可以下载cm fonts直接下载到我的电脑（但它们的格式我无法打开，而且我已经尝试了所有方法）http://sourceforge.net/projects/cm-unicode/
我打算制作我的图表>导出到 Adobe Illustrator 或 Inkscape 并在其中写入我的组标签：

像这样：
答案1
嗯，迟做总比不做好！:-)
该解决方案依赖于修改生成的代码matlab2tikz，因此它可能对您来说是或可能不可接受。
我将首先展示整个代码和输出，然后解释我的更改。

垂直红线
我决定通过创建红线并应用适当的样式来绘制红线extra x ticks。相关代码位于环境选项列表的末尾axis，在此处重现：
extra x ticks={6,12,...,24}, % locations of the red lines
extra x tick style={ % style for the extra red lines
tickwidth=6ex, % length of the extra red lines from top to bottom
tick align=center, % draw extra red lines centered about the axis grid
tick style={ultra thick,red}, % set line thickness and color
xticklabel={}, % do not label the extra ticks
xtick pos=left, % draw extra ticks only on the "left" (bottom), not the top
},
注释描述了每个设置的功能。当然，您可以根据自己的喜好自定义这些设置。
下方有患者标签
对于组标签（患者 1、2 等），我将其添加clip=false到选项列表中axis，以防止这些多余的标签被剪掉。
放置这些标签所需的其余代码以\foreach循环的形式位于环境的最末端axis：
\foreach \locn/\num in {3/1,9/2,15/3,21/4} {
\edef\temp{\noexpand\path (xticklabel cs:0) -| (\locn,0) node[pos=0.5] {Patient \num};}
\temp % solution from https://tex.stackexchange.com/questions/24539/
}
我使用了以下解决方案如何\foreach在axis环境中使用pgfplots中使用？解决\foreach内部axis环境中的一些扩展困难。的扩展将从刻度标签的底部标记到\temp“患者 n”标签的所需坐标。然后，将节点放置在此路径的中点（转折点）下方。-| \pathx
