Bug report

When using a very long FancyArrowPatch with connectionstyle="arc3", subsequent axes autoscaling can badly squash the figure's content. Example below exhibits the problem, but more extreme squashing can easily be obtained. Possibly this is not limited to FancyArrowPatch?

Code for reproduction

import matplotlib
import matplotlib.pyplot as plt

fap = matplotlib.patches.FancyArrowPatch(
    (10, 10),
    (20, 2e4),
    mutation_scale=50,
    connectionstyle="arc3,rad=0.3",
)

_, ax = plt.subplots()
ax.add_patch(fap)
ax.set_title(f"matplotlib {matplotlib.__version__}")
ax.autoscale_view()
ax.figure.savefig("curved-arrow.png")

Actual outcome

curved-arrow

Expected outcome

The axes view should span the drawn content. Any control point(s) required for the arc should be ignored.

Matplotlib version

  • Operating system: Linux
  • Matplotlib version: 3.3.4
  • Matplotlib backend: Reproducible with at least GTK3Agg and agg.
  • Python version: 3.9

Matplotlib installed via pip.

This is a duplicate of #19174, I believe.

I don't think it is; #19214 seems to fix #19174 but not this.
