How to shift the colorbar position to right in matplotlib?

To shift the colorbar position to right in matplotlib, we can take the following steps −

Steps

Import numpy and matplotlib.
Set the figure size and adjust the padding between and around the subplots.
Initialize a variable N to store the number of sample data.
Create x and y data points using numpy.
Create a scatter plot using scatter() method with x and y data points.
Add a colorbar to a plot, use the pad value for horizontal shift towards right or left.
To display the figure, use show() method.

Example

# Import numpy and matplotlib
import numpy as np
from matplotlib import pyplot as plt

# Set the figure size
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

N = 100

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

# Scatter plot with x and y data points
s = plt.scatter(x, y, c=x, cmap='hot', marker='*')

# Add a colorbar with pad value
plt.colorbar(s, shrink=0.9, pad=0.1)

# Display the plot
plt.show()

Output

It will produce the following output −

If you would like to set the colorbar to the left, then use the location parameter as shown below −

plt.colorbar(s, shrink=0.9, pad=0.1, location="left")

With this line in the code, we will have the output as follows −
