Latest proplot version incompatible with matplotlib 3.5

[beckermr]

Description

I think v0.9.5 might be incompatible with matplotlib 3.5.0. I installed from conda-forge so we can repin.

Steps to reproduce

A "Minimal, Complete and Verifiable Example" will make it much easier for maintainers to help you.

# your code here
# we should be able to copy-paste this into python and exactly reproduce your bug

fig, axs = pplt.subplots(nrows=3, ncols=3)

Expected behavior: [What you expected to happen]

A plot without a traceback?

Actual behavior: [What actually happened]

An error.

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.

# your code here, if applicable
import matplotlib.pyplot as plt

Proplot version

Paste the results of import matplotlib; print(matplotlib.__version__); import proplot; print(proplot.version)here.

>>> import matplotlib; print(matplotlib.__version__); import proplot; print(proplot.version)
3.5.0
0.9.5

I think we should add a new upper bound on conda-forge maybe?

I should get to a full 3.5 compatibility release by the end of the year soon, but for the time being I'll keep this issue pinned.

(For those reading this thread -- to use proplot, please either downgrade matplotlib to version 3.4.3 until this issue is closed, or install the development version with pip install git+https://github.com/lukelbd/proplot).

[beckermr]

Thank you!

[swamidass]

Just got this error too. Please add the matlab version to the pip package as a requirement?

[Mickychen00]

Was this issue closed? In its stable version, I still cannot use matplotlib when its version is higher than 3.4.3

[lukelbd]

I just submitted a release v0.9.7 to pypi that updates v0.9.5 with the requirement matplotlib>=3.3.0,<3.5.0 and addresses numpy's deprecation of python-type aliases like np.int (v0.9.6 didn't include the numpy fixes). Now pip install proplot should enforce a compatible matplotlib version, as I think conda install proplot already does.

Originally I was hoping to do the v0.10.0 release that adds matplotlib 3.5.X compatibility + other fixes/improvements/tests. But obviously the above timeline didn't work out -- I've had to take another hard step back from proplot as I finish my PhD.

I still personally use proplot every day in my work, and I plan to continue using it throughout my career, so I have no plans to abandon this project. Should finally have time to work on proplot this late spring/summer, and I'm looking into funding sources + options for building more of a community around this project (i.e., not just me -- hence the move to the "proplot-dev" organization) so that development can be less erratic going forward.
