matplotlib < 3.7 requirement?

[jameswilburlewis]

I'm glad to see basemap is still being developed! Are there any plans to support more recent versions of matplotlib? We recently patched some code to remove a reference to legendHandles (now deprecated and removed from matplotlib), but this caused a version conflict with matplotlib<3.7 from basemap, and matplotlib >= 3.7 for legend_handles. We were able to resolve the conflict with a version check, but it would be great if basemap didn't have the upper limit on matplotlib versions.

Hi @jameswilburlewis! In principle it should be no problem to upgrade the matplotlib requirements. The upper pin is there based on the latest matplotlib version at the time the latest basemap was released.

I can take a look to the requirements files in the following days to keep them up to date and release a new patch version for basemap.

The basemap hotfix release 1.3.7 is now available on PyPI. I will also trigger a rebuild for the conda-forge package soon.

I upgraded several version pins apart from matplotlib, you can see all the changes here: v1.3.6...v1.3.7.

@jameswilburlewis Finally basemap 1.3.7 is available both on PyPI and conda-forge for Windows and GNU/Linux, with all the requirements up to date, this should mitigate your issues in spedas/pyspedas#461.

If something is still not working for you, feel free to reopen the issue and I will see what I can do.
