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

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



.. code-block:: python

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

    NUM = 250

    ells = [Ellipse(xy=np.random.rand(2) * 10,
                    width=np.random.rand(), height=np.random.rand(),
                    angle=np.random.rand() * 360)
            for i in range(NUM)]

    fig, ax = plt.subplots(subplot_kw={'aspect': 'equal'})
    for e in ells:
        ax.add_artist(e)
        e.set_clip_box(ax.bbox)
        e.set_alpha(np.random.rand())
        e.set_facecolor(np.random.rand(3))

    ax.set_xlim(0, 10)
    ax.set_ylim(0, 10)

    plt.show()

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

Draw many ellipses with different angles.




.. code-block:: python


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

    delta = 45.0  # degrees

    angles = np.arange(0, 360 + delta, delta)
    ells = [Ellipse((1, 1), 4, 2, a) for a in angles]

    a = plt.subplot(111, aspect='equal')

    for e in ells:
        e.set_clip_box(a.bbox)
        e.set_alpha(0.1)
        a.add_artist(e)

    plt.xlim(-2, 4)
    plt.ylim(-1, 3)

    plt.show()
