matplotlib:在不更改纵横比的情况下设置图形的宽度或高度 [英] matplotlib: Set width or height of figure without changing aspect ratio

问题描述

我想选择图形的宽度，同时仍然让matplotlib选择合适的纵横比.我知道的每一种改变图形大小的方法都需要一个 (width, height) 元组，它强制一定的纵横比.有什么方法可以仅指定宽度(或仅高度)并允许matplotlib选择合适的宽高比?

I'd like to choose the width of a figure, while still letting matplotlib choose the aspect ratio that it finds suitable. Every method I know to change the figure size requires a (width, height) tuple, which forces a certain aspect ratio. Is there any way to specify just the width (or just the height) and allow matplotlib to choose a suitable aspect ratio?

推荐答案

我了解到matplotlib实际上只是对所有图形使用恒定的默认图形大小.此值存储在 rcParams 中，并且可以使用

I've learned that matplotlib actually just uses a constant default figure size for all figures. This value is stored in the rcParams, and can be viewed with

plt.rcParams["figure.figsize"]

这会为我返回 [6.0，4.0] .

如果您想保持相同的宽高比(即纵横比")，例如，您可以将其加倍:

If you want to keep the same width to height ratio (ie "aspect ratio"), you can, for example, double it with:

plt.rcParams["figure.figsize"] = [2 * i for i in plt.rcParams["figure.figsize"]]
