How to plot a 2D histogram in Matplotlib?

MatplotlibPythonData Visualization

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
