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
# Fixing random state for reproducibility
np.random.seed(19680801)
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.
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()
