如何创建子图、添加图例、删除 1000 个分隔符以及添加标题？

Question

我有 8 张 tikzpicture，需要将它们合并成一张适合 A4 纸大小的图片，这样顶行有 3 张图，第二行有 3 张图，底行有 2 张图。底行的图也应居中。

另外，我想知道如何删除 1,000 个逗号分隔符，以便显示“2000”而不是“2,000”。

我还想为所有图表添加一个位于图表下方的标题。

最后，我还想为整个图形添加一个标题。

这是我目前拥有的代码：

我建议为图表定义简写，这样最后的代码就不会那么混乱，也更容易维护。

该解决方案将缩放图表以适合文本列的三分之一。

Answer 3

编辑：

• 对于每个图下方的子标题，需要将其插入subfigure或subfloats环境中，这样才能编写 sub.captions。
• 该软件包的最新版本（v 1.3）subcaption定义了这两种环境。
• 在下面的 MWE 中，我决定使用它，subfloat因为它的代码较短。
• 由于子图的样式设置有很多相同之处，因此将它们分组到公共的 中是有意义的\pgfplotsset。这可以使代码更短更清晰。

附录：

• 根据我的喜好，图形的宽度不应大于文本区域的宽度。如果出于某种原因（例如图像可以更大），它应该只在其外边框上突出文本区域，如下面的 MWE 所示。
• 您可能考虑为所有图使用一个共同的图例。例如，它可以放置在最后一个子图的右侧，参见下面的 MWE。
