How to create a standard colorbar for a series of plots in python

To create a standard colorbar for a series of plots in Python, you can use the matplotlib library. A colorbar is a common way to represent the mapping of numerical values to colors in a plot. Here's a step-by-step guide:

  • Import the necessary libraries:
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.colors import Normalize
from matplotlib.colorbar import ColorbarBase
  • Create your series of plots. You can use a loop or any other method to generate your plots. For this example, let's create three simple plots:
# Create some example data
x = np.linspace(0, 2 * np.pi, 100)
y1 = np.sin(x)
y2 = np.cos(x)
y3 = np.sin(2 * x)

# Create three plots
plt.figure(figsize=(12, 4))
plt.subplot(131)
plt.plot(x, y1)
plt.title('Plot 1')

plt.subplot(132)
plt.plot(x, y2)
plt.title('Plot 2')

plt.subplot(133)
plt.plot(x, y3)
plt.title('Plot 3')
  • Define a color map and normalize your data. You can adjust the colormap to your preference. Here, we'll use the viridis colormap:
cmap = plt.get_cmap('viridis')
norm = Normalize(vmin=0, vmax=2 * np.pi)  # Adjust the min and max values as needed
  • Create the colorbar using ColorbarBase and specify its location and the colormap:
# Create the colorbar
colorbar_axes = plt.axes([0.92, 0.1, 0.03, 0.8])  # Define the location and size of the colorbar
colorbar = ColorbarBase(colorbar_axes, cmap=cmap, norm=norm)
colorbar.set_label('Color Scale')  # Set the label for the colorbar
  • Show the plots and colorbar:
plt.tight_layout()
plt.show()

This code will create three plots side by side and add a colorbar to the right of the plots. You can adjust the location and size of the colorbar by modifying the colorbar_axes variable.

Feel free to replace the example data and plots with your own data and plots as needed.
