============
Ellipse Demo
============

Draw many ellipses. Here individual ellipses are drawn. Compare this
to the :doc:`Ellipse collection example
</gallery/shapes_and_collections/ellipse_collection>`.

===============
Ellipse Rotated
===============

Draw many ellipses with different angles.

    import matplotlib.pyplot as plt
    import numpy as np
    from matplotlib.patches import Ellipse

    angle_step = 45  # degrees
    angles = np.arange(0, 360, angle_step)

    ax = plt.subplot(aspect='equal')

    for angle in angles:
        ellipse = Ellipse((0, 0), 4, 2, angle=angle, alpha=0.1)
        ax.add_artist(ellipse)

    plt.xlim(-2.2, 2.2)
    plt.ylim(-2.2, 2.2)

    plt.show()
