Line2D and PathPatch have different defaults for capstyle and joinstyle #18597
Description
Describe the issue
Noticed while working on #18579.
Summary
Capstyle and joinstyle of PathPatch and Line2D differ:
| c apstyle | joinstyle | |
|---|---|---|
| Line2D | projecting | round |
| PathPatch | butt | miter |
as can be seen in:
import matplotlib.pyplot as plt
from matplotlib.patches import Path, PathPatch
x = [0, 5, 0]
y = [0, 0, 2]
ax = plt.gca()
ax.axis('equal')
ax.set_xlim(-1, 7)
ax.plot(x, y, lw=20, alpha=0.5, label='Line2D')
ax.add_patch(PathPatch(Path(list(zip(x, y))), fill=False, ec='r', lw=20, label='PathPatch', capstyle='butt'))
ax.legend()
Proposed fix
This is unexpected and must at least be documented.
I'm unsure if we can afford to change the default of PathPatch (if we make a breaking change, it must be on PathPatch, Line2D is too often used and we cannot affort to change that.
Opinions welcome.
