Bug report
Bug summary
Related to #3038, #2863 and this stackoverflow bug: if only identical (or one single) points are given,
This seems to still be a bug when using mincnt > 0
Code for reproduction
import numpy as np
import matplotlib.pyplot as plt
mytens = [np.array([[-1, 1], [1, 1]]),
np.array([[-1, 1], [-1, -1], [-1, -1]]),
np.array([[-1, 1]])]
fig, axs = plt.subplots(nrows=2, ncols=2, sharex="all", sharey="all", squeeze=False)
axs[0, 0].hexbin(
x=mytens[0][:, 0],
y=mytens[0][:, 1],
mincnt=1,
gridsize=4
)
axs[0, 0].set_title("correct point 1")
axs[0, 1].hexbin(
x=mytens[1][:, 0],
y=mytens[1][:, 1],
mincnt=1,
gridsize=4
)
axs[0, 1].set_title("correct point 2")
axs[1, 0].hexbin(
x=mytens[2][:, 0],
y=mytens[2][:, 1],
mincnt=1,
gridsize=4
)
axs[1, 0].set_title("actual point not plotted, instead at 0,0!")
axs[1, 1].hexbin(
x=mytens[2][:, 0],
y=mytens[2][:, 1],
# mincnt=0, # if not given, 0 is assigned internally
gridsize=4
)
axs[1, 1].set_title("actual point plotted, expected behaviour")
plt.show()
Actual outcome
Expected outcome
Point on the bottom left should be on the left top. The plotted point (0,0) does not even exist in the given data.
