Bug report

As already stated in this stack overflow thread, when drawing arrows with the arrow()-method, the scale of the plot is not adjusted as expected. A workaround is to set the limits of the plot manually or to plot additional, invisible points near the arrows.

Code for Reproducing the bug

import matplotlib.pyplot as plt
import matplotlib
import sys

print(matplotlib.__version__)
print(sys.version)
fig, ax = plt.subplots()
#ax.set_xlim(0, 5)
#ax.set_ylim(0, 5)
ax.arrow(1, 1, 1, 1)
plt.show()

Output:

3.0.1
3.7.0 (default, Oct  9 2018, 10:31:47) 
[GCC 7.3.0]

Outcome with setting limits manually

I installed matplotlib by using anaconda.

I didn't specify a channel, so I guess it was the main channel.
