How do I change the figure size with subplots?
提问by Brian
I came across this examplein the Matplotlib website. I was wondering if it was possible to increase the figure size.
我在 Matplotlib 网站上遇到了这个例子。我想知道是否可以增加图形大小。
I tried with
我试过
f.figsize(15,15)
but it does nothing.
但它什么也不做。

If you already have the figure object use:
如果您已经拥有图形对象，请使用：
f.set_figheight(15)
f.set_figwidth(15)
But if you use the .subplots() command (as in the examples you're showing) to create a new figure you can also use:
但是，如果您使用 .subplots() 命令（如您展示的示例中所示）创建一个新图形，您还可以使用：
f, axs = plt.subplots(2,2,figsize=(15,15))

Alternatively, create a figure()object using the figsizeargument and then use add_subplotto add your subplots. E.g.
或者，figure()使用figsize参数创建一个对象，然后用于add_subplot添加子图。例如
import matplotlib.pyplot as plt
import numpy as np
f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')
Benefits of this method are that the syntax is closer to calls of subplot()instead of subplots(). E.g. subplots doesn't seem to support using a GridSpecfor controlling the spacing of the subplots, but both subplot()and add_subplot()do.
这种方法的好处是语法更接近于调用subplot()而不是subplots()。例如，次要情节似乎没有使用支持GridSpec用于控制次要情节的间距，但都subplot()和add_subplot()做的。
