Matplotlib: Aligning y-axis labels in stacked scatter plots

Aligning y-axis labels in stacked scatter plots in Matplotlib can be achieved by using the yticks and yticklabels functions to manually set the positions and labels for the y-axis ticks. Here's a step-by-step guide to aligning y-axis labels in stacked scatter plots:

import matplotlib.pyplot as plt import numpy as np # Sample data for stacked scatter plots data1 = np.random.rand(10) * 10 data2 = np.random.rand(10) * 10 + 20 data3 = np.random.rand(10) * 10 + 40 # Create subplots fig, ax = plt.subplots() # Plot the scatter plots ax.scatter(data1, range(len(data1)), label='Data 1', color='red') ax.scatter(data2, range(len(data2)), label='Data 2', color='green') ax.scatter(data3, range(len(data3)), label='Data 3', color='blue') # Set y-axis ticks and labels yticks_positions = np.arange(len(data1)) # Positions of the y-ticks ytick_labels = ['Item {}'.format(i+1) for i in range(len(data1))] # Labels for the y-ticks ax.set_yticks(yticks_positions) ax.set_yticklabels(ytick_labels) # Add a legend ax.legend() # Set labels and title ax.set_xlabel('X-axis') ax.set_ylabel('Y-axis') plt.title('Stacked Scatter Plots with Aligned Y-Axis Labels') # Show the plot plt.show()

In this example:

  1. We create sample data (data1, data2, and data3) for three scatter plots that will be stacked on the same y-axis.

  2. We create subplots and plot the scatter plots for the sample data.

  3. We manually specify the positions of the y-ticks using set_yticks and set the labels for the y-ticks using set_yticklabels.

  4. We add a legend to differentiate between the scatter plots.

  5. We set labels for the x-axis and y-axis and provide a title for the plot.

  6. Finally, we display the plot using plt.show().

You can adjust the ytick_labels list to match the labels you want to display for your data points. This approach allows you to align y-axis labels for stacked scatter plots in Matplotlib.
