Create 2D bar graphs in different planes#
Demonstrates making a 3D plot which has 2D bar graphs projected onto planes y=0, y=1, etc.
import matplotlib.pyplot as plt import numpy as np # Fixing random state for reproducibility np.random.seed(19680801) fig = plt.figure() ax = fig.add_subplot(projection='3d') colors = ['r', 'g', 'b', 'y'] yticks = [3, 2, 1, 0] for c, k in zip(colors, yticks): # Generate the random data for the y=k 'layer'. xs = np.arange(20) ys = np.random.rand(20) # You can provide either a single color or an array with the same length as # xs and ys. To demonstrate this, we color the first bar of each set cyan. cs = [c] * len(xs) cs = 'c' # Plot the bar graph given by xs and ys on the plane y=k with 80% opacity. ax.bar(xs, ys, zs=k, zdir='y', color=cs, alpha=0.8) ax.set_xlabel('X') ax.set_ylabel('Y') ax.set_zlabel('Z') # On the y axis let's only label the discrete values that we have data for. ax.set_yticks(yticks) plt.show()
