How to Change the Size of Matplotlib Figures?

python

There are different ways to change the size of Matplotlib figures depending on the specific use case. Here are some common approaches:

1. Set figure size when creating the plot:

import matplotlib.pyplot as plt

fig, ax = plt.subplots(figsize=(10, 5))
ax.plot(x, y)

This will create a figure with width 10 inches and height 5 inches.

2. Use rcParams to set default figure size:

import matplotlib.pyplot as plt
import matplotlib as mpl

mpl.rcParams['figure.figsize'] = (10, 5)

fig, ax = plt.subplots()
ax.plot(x, y)

This will set the default figure size to be 10 inches wide and 5 inches tall.

3. Use the set_size_inches method to dynamically change the size of a figure:

fig, ax = plt.subplots()
ax.plot(x, y)
fig.set_size_inches(10, 5)

This will change the size of the current figure to be 10 inches wide and 5 inches tall.

4. Use the subplots_adjust method to adjust the spacing around the figure:

fig, ax = plt.subplots()
ax.plot(x, y)
fig.subplots_adjust(left=0.2, right=0.8, top=0.8, bottom=0.2)

This will adjust the spacing around the plot within the figure. The values of left, right, top, and bottom specify the fraction of the figure width/height that is used for spacing.
