Bug report
Bug summary
MatPlotLib axes_rgb cannot plot images of non-square dimensions, error in checking dimensions of red, green, and blue channels. Line 206 of mpl_toolkits.axes_grid1.axes_rgb.py erroneously swaps nx and ny.
Code for reproduction
- A minimum code snippet required to reproduce the bug, also minimizing the number of dependencies required
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1.axes_rgb import RGBAxes
r = np.zeros((40, 100))
g = np.zeros_like(r)
b = np.zeros_like(r)
fig = plt.figure(2)
ax = RGBAxes(fig, [0.1, 0.1, 0.8, 0.8])
ax.imshow_rgb(r, g, b)
plt.show()Actual outcome
