matplotlib 中的子图使用轴法时的高分辨率图

Question

When creating a figure using plt.figure , one can set its size and resolution in the following way:

plt.figure(num=1, figsize=(6, 4), dpi=150)

How can this be obtained when creating a figure using the following code?

fig, ax = plt.subplots()

I've tried the code bellow but I get the error TypeError: 'Figure' object is not callable

ax.figure(num=1, figsize=(6, 4), dpi=150)

Thanks for your help and suggestions!

Answer 1

plt.subplots() supports all the keyword parameters of plt.figure() , so to change the resolution, just do:

fig, ax = plt.subplots(dpi=150)

Take a look at the docs:

• https://matplotlib.org/3.2.1/api/_as_gen/matplotlib.pyplot.subplots.html

EDIT: The reason your code isn't working is because ax.figure is a Figure object, not a function. This is why it's "not callable."
