latex绘制子图，并为子图添加
如下代码所示：
通过\subfigure绘制子图，\centering使图片居中，可以直接在子图中为为图片添加标注，如代码中的{\scriptsize{误差均值}}，该命令表示在子图上面添加标注。有时需要同时在子图的左边也添加竖排标注，但是会出问题。因此我们需要改为按照子图的形式添加标注。

排版出错的问题，如下：
因为在添加上表的同时又添加了左标注，造成标注和colorbar串行，而除了第一行子图出错外其他的均正常显示。这个表明在我们绘制子图时，同一行子图的格斯要一致。我们可以以绘制子图的形式绘制上标注。如图下所示：

如上所示，解决串行问题。
需要额外表明的是：在同一行的子图中，所有图的宽度之和大于行宽的时候，图片也会自动换行显示，因此在图片大小分配时也要额外注意。
