To plot a 2D histogram in matplotlib, we can take the following steps −
Set the figure size and adjust the padding between and around the subplots.
Create x and y data points using numpy.
Create a figure and a set of subplots.
Plot x and y using hist2d() method.
Set the title of the plot.
To display the figure, use show() method.
Example
import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
x = 2 * np.random.randn(5000)
y = x + np.random.randn(5000)
fig, ax = plt.subplots()
_ = ax.hist2d(x[::10], y[::10])
ax.set_title('2D Histogram')
plt.show()Output
