我使用以下方法导出matlab了几个图tikzmatlab2tikz。其中许多都使用颜色，并且通常可以分组。然而，在 matlab 中为子图组添加一个颜色条并使用导出它似乎很困难matlab2tikz。我决定单独导出所有图，然后重新组合它们TeX。这使我对图的子标题有了额外的控制权。
我现在正在努力对齐颜色条到不同子图的轴。我知道，使用 pgfplot 并仅从 matlab 导出数据可能会更容易。但是，由于时间有限且难以访问 matlab 文件，目前这不是一个选项。
我想要实现的目标：将颜色条左侧与第一个子图的 y 轴对齐。将颜色条右侧与第二个子图的右侧 y 轴对齐在其他图中，将颜色条放在图的右侧也会出现类似的问题（我的印象是，由于子图包的排列，这可能不是完全相同的问题。）如果你们有建议如何将子标题置于中央在子图的 y 标签下方，我会很高兴。您会发现附加了 MWE，图中的颜色被忽略了，数据也是如此。提前致谢！

答案1
您可以手动设置位置at={(0.252,0.0)},anchor=north west,和宽度width=11.156cm,（尝试并出错）。您还必须删除%height=0pt, %width=0pt,。
