axis limits come out reversed a lot #334
Description
Description
Right now in many cases, the plot limits come out reverse (e.g., the x-axis goes from 1 to -4 instead of -4 to 1).
Steps to reproduce
A "Minimal, Complete and Verifiable Example" will make it much easier for maintainers to help you.
import proplot as pplt
import numpy as np
rng = np.random.RandomState(seed=10)
x = rng.uniform(size=1000)*4 - 6
y = rng.uniform(size=1000)*2 + 6
fig, axs = pplt.subplots()
axs.hexbin(x, y)Expected behavior: axis limits numerically ordered (should be -6 to -2)
Actual behavior: came out reversed (-2 to -6)
Equivalent steps in matplotlib
Please try to make sure this bug is related to a proplot-specific feature. If you're not sure, try to replicate it with the native matplotlib API. Matplotlib bugs belong on the matplotlib github page.
import matplotlib.pyplot as plt
import numpy as np
rng = np.random.RandomState(seed=10)
x = rng.uniform(size=1000)*4 - 6
y = rng.uniform(size=1000)*2 + 6
fig, axs = plt.subplots(nrows=1, ncols=1)
axs.hexbin(x, y)Proplot version
Paste the results of import matplotlib; print(matplotlib.__version__); import proplot; print(proplot.version)here.

This is related to #300 (also documented on this page). Proplot automatically reverses the axis when it detect "dependent" variable coordinates and the axes were not previously fixed -- however this behavior should definitely be disabled for
hexbinandhist2d, and it looks like this used to be disabled forhistandhisthbut the #191 fix is now obsolete. Sorry for the annoying behavior! I'll fix this later today.Note also that the #300 fix make this feature more conservative; for example when passing stuff to
ax.plot(x, y)an axis will only be reversed if 1) the x limits were not previously fixed with e.g.set_xlimand 2) the x coordinates are monotonically decreasing rather than simply having a negative initial step size.beckermr commentedon Feb 3, 2022
Thank you!
Disable hexbin/hist/hist2d autoreverse (fix #334)

Thank you! Looking forward to a release with the patch!

I'm still seeing this for the
quivercommand, even in new releases, does that need to be addressed separately?
