A ConnectionPatch is sometimes not shown on one of the plots, depending on the position of the axesA and axesB subplots.
A reproducing example, with only minor changes to the ConnnectionPatch example from the docs:
from matplotlib.patches import ConnectionPatch
import matplotlib.pyplot as plt
fig, (ax1, ax2) = plt.subplots(1,2)
xy = (0.3, 0.2)
coordsA = "data"
coordsB = "data"
con = ConnectionPatch(xyA=xy, xyB=xy, coordsA=coordsA, coordsB=coordsB,
axesA=ax1, axesB=ax2,
arrowstyle="->", shrinkB=5)
ax1.add_artist(con)
# This works fine:
#con = ConnectionPatch(xyA=xy, xyB=xy, coordsA=coordsA, coordsB=coordsB,
# axesA=ax2, axesB=ax1,
# arrowstyle="->", shrinkB=5)
#ax2.add_artist(con)
ax1.set_xlim(0, 1)
ax1.set_ylim(0, 1)
ax2.set_xlim(0, .5)
ax2.set_ylim(0, .5)
