[Matplotlib-users] Axis default limits with a Circle patch

[Amit S. <ami...@gm...>]

Hi all,

Consider the following code:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.gca()
circle = plt.Circle((0, 0), radius = 0.5)
ax.add_patch(circle)
print(plt.axis())
plt.show()

The default axis limits are printed as:

(0.0, 1.0, 0.0, 1.0)

I am not sure why this is the case. So, I would like to learn why?

PS: I know I can just do plt.axis('scaled') so that I can see the entire circle.

I also asked this on SO, so feel free to answer there as well:

Thanks,
-Amit.
