问题：
在论文中，我们会经常看到下面展示的这种图片，对多幅子图进行对比展示，下标（可选择是否需要），并对数据的每个类别用不同的颜色进行注释，下标（不需要），但是需要换成文字注释。虽然可以选择在PPT或者其他画图软件画好，然后简单的直接将一整张图导入到Latex，但是这会造成一个小瑕疵， 图片里面的字体大小和正文字体大小可能会不一样，并且图放大或者缩小，字体也容易变形，我觉得这是一个容易忽视但又十分重要的问题。
思考：
考虑能否在Latex里面把这种颜色方块注释也当作很多个小图片来排版，然后文字注释可以直接在Latex里面写 ，最终解决原来那种操作的小瑕疵，尝试成功，分享给需要写论文的小朋友~~
