我并排显示了两个不具有相同 xmax 和 ymax 的 pgfplots。在第一种情况下 (xmin=-1,xmax=3,ymin=-1,ymax=11)，两个图具有相同的高度（参见示例 1）。在第二种情况下 (xmin=-1,xmax=12,ymin=-1,ymax=7)，两个图的高度不完全相同。但我希望它们具有相同的高度（参见示例 2）。当 ymax-ymin 小于 xmax-xmin 时，是否必须执行某些特定操作？

答案1
我认为您看到的内容可能与 的记录行为有关axis equal image。使用该设置，pgfplots将很乐意重新缩放 ，axis使其不再符合height/width设置。axis equal另一方面，设置将通过调整轴限制来尊重height/设置。width
根据您的要求，不使用axis equal image或使用axis equal可能是一种解决方案，此外还明确设置和width。height（我width=6cm, height=4.5cm在下面使用了。）
与您的问题无关，但您可能对groupplots下面演示的图书馆感兴趣。
