Python - matplotlib: Aligning y-axis labels in stacked scatter plots

In Matplotlib, aligning y-axis labels in stacked scatter plots can be achieved by adjusting the position of the y-axis ticks and labels. You can do this by setting the yticks and yticklabels properties of the y-axis. Here's how you can align the y-axis labels in stacked scatter plots:

import matplotlib.pyplot as plt import numpy as np # Generate some sample data x = np.arange(10) y1 = np.random.rand(10) * 10 y2 = np.random.rand(10) * 10 y3 = np.random.rand(10) * 10 # Create a figure and axis fig, ax = plt.subplots() # Plot the stacked scatter plots ax.scatter(x, y1, label='Group 1') ax.scatter(x, y2, label='Group 2') ax.scatter(x, y3, label='Group 3') # Adjust the position of y-axis ticks and labels ax.set_yticks(np.arange(0, 11, 2)) # Adjust the range and interval as needed ax.set_yticklabels([f'{i:.1f}' for i in np.arange(0, 11, 2)]) # Format y-axis labels # Add legend ax.legend() # Show plot plt.show()

In this example:

  • We generate some sample data for three groups (y1, y2, y3).
  • We plot the stacked scatter plots using the scatter function.
  • We adjust the position of the y-axis ticks using set_yticks and provide a list of desired tick positions.
  • We also adjust the y-axis labels using set_yticklabels and provide a list of formatted labels corresponding to the tick positions.
  • Finally, we add a legend to the plot.

You can adjust the range, interval, and format of the y-axis ticks and labels according to your specific requirements.
