如何使子图看起来可见，并且并排子图之间的垂直空间较小，并保持相同的大小？

目前，我正在使用此代码将子图生成为一个图。

以下输出如下所示。 示例输出

当前的问题是

  • 图题无法展示所有信息。

  • 子图不可见

  • 我想让子图具有相同的尺寸（高度和宽度）

有没有办法或特定的代码来解决这些问题？

答案1

看起来您需要限制 10 个图表的高度。请务必指定该选项keepaspectratio以确保避免失真。

按照以下示例所示的代码可能会有所帮助。（请确保demo在实际文档中删除该选项。）

单独的评论：不要混淆图例和标题。后者通常应该简短明了，让读者一眼就能了解内容figure。图例可以（也应该）尽可能长，以深入解释读者从阅读图表中应该获得什么。

The figures in the left-hand column represent the state trajectories of the BI (bilinear incidence) models, and the figures in the right-hand column correspond to that of HSI (half-saturated incidence) models. The parameter values and initial conditions that are used in both models are listed in Table~\ref{tab:table2}. Observe that the endemic equilibrium point ($E_{AH}^* = (S_b^*, I_b^*, S_h^*, I_a^*, R_h^*) = (1.3950, 1166.4224, 280706.4850, 0.1329, 1342.5412)$) is consistent with the steady state values of $S_b$, $I_b$, $S_h$, $I_a$, and  $R_h$ shown in the left-hand column.
