# Fill plot demo

First example showcases the most basic fill plot a user can do with matplotlib.

Second example shows a few optional features:

> - Multiple curves with a single command.
> - Setting the fill color.
> - Setting the opacity (alpha value).

    import numpy as np
    import matplotlib.pyplot as plt

    x = np.linspace(0, 1, 500)
    y = np.sin(4 * np.pi * x) * np.exp(-5 * x)

    fig, ax = plt.subplots()

    ax.fill(x, y, zorder=10)
    ax.grid(True, zorder=5)

    x = np.linspace(0, 2 * np.pi, 500)
    y1 = np.sin(x)
    y2 = np.sin(3 * x)

    fig, ax = plt.subplots()
    ax.fill(x, y1, 'b', x, y2, 'r', alpha=0.3)
    plt.show()
