How do I use colorbar with hist2d in matplotlib.pyplot?

To use colorbar with hist2d in matplotlib.pyplot, we can take the following steps.

Steps

Set the figure size and adjust the padding between and around the subplots.
Initialize a variable "N" for the number of sample data.
Createx and y data points using numpy.
Create a figure and a set of subplots using subplots() method.
Make a 2D histogram plot using hist2D().
Create a colorbar for the hist2d scalar mappable instance.
To display the figure, use Show() method.

Example

from matplotlib.colors import LogNorm
import matplotlib.pyplot as plt
import numpy as np

# Set the figure size
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True

# Number of sample data
N = 1000

# Create x and y data points
x = np.random.rand(N)
y = np.random.rand(N)

fig, ax = plt.subplots()

# 2D histogram plot with x and y
hh = ax.hist2d(x, y, bins=40, norm=LogNorm())

fig.colorbar(hh[3], ax=ax)

# Display the plot
plt.show()
