# Demo of 3D bar charts

A basic demo of how to plot 3D bars with and without shading.

    import numpy as np
    import matplotlib.pyplot as plt
    from mpl_toolkits.mplot3d import Axes3D

    # setup the figure and axes
    fig = plt.figure(figsize=(8, 3))
    ax1 = fig.add_subplot(121, projection='3d')
    ax2 = fig.add_subplot(122, projection='3d')

    # fake data
    _x = np.arange(4)
    _y = np.arange(5)
    _xx, _yy = np.meshgrid(_x, _y)
    x, y = _xx.ravel(), _yy.ravel()

    top = x + y
    bottom = np.zeros_like(top)
    width = depth = 1

    ax1.bar3d(x, y, bottom, width, depth, top, shade=True)
    ax1.set_title('Shaded')

    ax2.bar3d(x, y, bottom, width, depth, top, shade=False)
    ax2.set_title('Not Shaded')

    plt.show()
