matplotlib pyplot:子图大小 [英] matplotlib pyplot: subplot size

问题描述

如果我绘制一个如下图，它的大小为 (x * y).

If I plot a single graph as below, it will be of size (x * y).

import matplotlib.pyplot as plt
plt.plot([1, 2], [1, 2])

但是，如果我在同一行中绘制 3 个子图，则每个子图的大小都是 ((x/3) * y).

However, if I plot 3 sub-graphs in the same row, each of them will be of size ((x / 3) * y).

fig, ax = plt.subplots(1, 3, sharey = True)
for i in range(3):
    ax[i].plot([1, 2], [1, 2])

如何获得这 3 个子图，每个子图的大小为 (x * y)?

How can I obtain these 3 subplots, each of which is of size (x * y)?

推荐答案

图形对象的默认大小不知道子图的数量.您可以根据自己的需要制作图形，但可以更改图形大小.

The figure object has a default size that does not know about the number of subplots. You can change the figure size when you make the figure to suit your needs though.

import matplotlib.pyplot as plt

nx = 3
ny = 1

dxs = 8.0
dys = 6.0

fig, ax = plt.subplots(ny, nx, sharey = True, figsize=(dxs*nx, dys*ny) )
for i in range(nx):
    ax[i].plot([1, 2], [1, 2])
