Set size of subplot in matplotlib
提问by Andrej
I wonder how to set the size of the subplot when figure contains multiple subplots (5 × 2 in my case). No matter how big I allow the whole figure to be, the subplots always seem to be small. I would like to have direct control of the size of the subplot in this figure. The simplified version of the code is pasted below.
我想知道当图形包含多个子图（在我的情况下为 5 × 2）时如何设置子图的大小。无论我允许整个图形有多大，次要情节似乎总是很小。我想直接控制此图中子图的大小。代码的简化版本粘贴在下面。
import numpy as np
import matplotlib.pyplot as plt
x = np.random.randn(20)
y = np.random.randn(20)
fig = plt.figure(figsize=(20, 8))
for i in range(0,10):
ax = fig.add_subplot(5, 2, i+1)
plt.plot(x, y, 'o')
ax.xaxis.set_visible(False)
ax.yaxis.set_visible(False)
# x and y axis should be equal length
x0,x1 = ax.get_xlim()
y0,y1 = ax.get_ylim()
ax.set_aspect(abs(x1-x0)/abs(y1-y0))
plt.show()
fig.savefig('plot.pdf', bbox_inches='tight')

Just switch figure size width and height from:
只需从以下位置切换图形大小的宽度和高度：
fig = plt.figure(figsize=(20, 8))
to:
到：
fig = plt.figure(figsize=(8, 20))
to use the whole page for your plots.
将整个页面用于您的绘图。
