How to make Matplotlib scatterplots transparent as a group?
To make matplotlib scatterplots transparent as a group, we can change the alpha value in the scatter() method argument with a different group value.
Steps
Set the figure size and adjust the padding between and around the subplots.
Make a method to return a grouped x and y points.
Get group 1 and group 2 data points.
Plot group1, x and y points using scatter() method with color=green and alpha=0.5.
Plot group2, x and y points using scatter() method with color=red and alpha=0.5.
To display the figure, use show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True def get_group_points(): return np.random.rand(100), np.random.rand(100), group_1 = get_group_points() group_2 = get_group_points() plt.scatter(group_1[0], group_1[1], color='green', alpha=0.5, s=100) plt.scatter(group_2[0], group_2[1], color='red', alpha=0.5, s=100) plt.show()
