Bug summary
The picker of FancyArrowPatch will not work with some arrow styles (see included example). Certain arrow styles will cause the picker to produce a pick event if the user clicks anywhere to the left of the arrow.
Code for reproduction
from matplotlib import pyplot as plt
from matplotlib import patches
def pick_event(event):
print("PICK", event.artist)
def main():
fig = plt.figure()
axes = fig.add_subplot(111)
axes.set_xlim((0, 10))
axes.set_ylim((0, 10))
arrow = patches.FancyArrowPatch(
(8, 2),
(9, 3),
# Uncommenting this will make the pick event be triggered every time I
# click to the left of the arrow.
# arrowstyle='-|>',
)
# Same thing happens with arrow.set_picker(True)
arrow.set_picker(4)
fig.canvas.mpl_connect('pick_event', pick_event)
axes.add_patch(arrow)
plt.show()
if __name__ == '__main__':
main()Actual outcome
(With the arrowstyle line uncommented)
A pick event is always triggered when clicking to the left of the arrow.
PICK FancyArrowPatch(8,2->9,3)
PICK FancyArrowPatch(8,2->9,3)
PICK FancyArrowPatch(8,2->9,3)
PICK FancyArrowPatch(8,2->9,3)
PICK FancyArrowPatch(8,2->9,3)
Expected outcome
The pick event is not triggered unless the user actually clicks on the arrow.
Matplotlib version
I tested this with two versions of matplotlib:
- version 2.0.0 installed via pip 9.0.1 using Python 2.7.12 included in ubuntu
- version 1.5.3 built from source using Python 2.7.11 built from source
