# Ellipse Demo¶

Draw many ellipses. Here individual ellipses are drawn. Compare this to the Ellipse collection example.

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:
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.

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)

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

plt.show()
