QRiS 0.1.7 Fails on Install looking for matplotlib

[joewheaton]

Sorry @philipbaileynar. Thanks for quick turn around... little tail chasing here. On my Windows 11 Machine with QGIS 3.24.3 and Python 3.9.5, install from zip fails with this message (different one, new dependency):

Couldn't load plugin 'qris_deploy' due to an error when calling its classFactory() method

Matt has a PR that shows a warning when this happens but still let's qris proceed. But I have not incorporated it yet.

However, we are going to use matplotlib all over the place. Our minimum version must have the matplotlib package.

Can you try installing the latest release (3.26 I think) and see if that works with qris 0.17

Okay....

• Uninstalled 3.24.3, (c. 7-8 minutes)
• Installed 3.26.3 (~ 5 min)

It actually recognized (even with complete uinstall and reinstall all the old Plugins. Same error as before. Then uninstalled 0.1.7 and reinstalled. Same error. Sorry Pip

I just happened to be using the Raster Value plugin and noticed that it uses plots. It's open source and so you can see that they support two plotting controls: matplotlib and QwtPlot.

@KellyMWhitehead I think this might be fixed no?

[KellyMWhitehead]

Yes, all good. We now have matplotlib up and running!
