How to build colorbars without attached plot in matplotlib?

To build colorbars without attached plot in matplotlib, we can take the following steps.

Steps

Set the figure size and adjust the padding between and around the subplots.
Create a figure and a set of subplots.
Adjust the subplot layout parameters.
Normalize the quaternion in place. Return the norm of the quaternion.
Get the colorbar instance (cb) with base colorbar and horizontal orientation.
To display the figure, use Show() method.

Example

import matplotlib.pyplot as plt
import matplotlib as mpl

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

# Create a figure and a set of subplots
fig, ax = plt.subplots()

# Adjust the subplot layout parameter
fig.subplots_adjust(bottom=0.5)

# Normalize
norm = mpl.colors.Normalize(vmin=5, vmax=10)

# Get the colorbar instance
cb = mpl.colorbar.ColorbarBase(ax, cmap=mpl.cm.cool, norm=norm, orientation='horizontal')

# Display the plot
plt.show()
