When I am passing legend parameter I am getting this error. If I don't pass legend, It works fine

What versions of fcp and matplotlib are you using?

Ok I suspected this. It is a known bug but I haven't had time to patch it because I'm focused on releasing v0.5.0. fcp 0.4.3 doesn't support matplotlib 3.5.3.

You can either downgrade your matplotlib (don't recall exactly which version works but around 3.1 I think) or upgrade to the beta version of fcp v0.5.0 (pip install fivecentplots==0.5.0b2)

Sorry for the inconvenience!

OK I decided to patch this after all since the newer version is still beta so now you can use v0.4.4 to avoid the legmarker issue with mpl 3.5.3. pip install fivecentplots --force-reinstall should take care of the upgrade for you.

But I strongly encourage migration to v0.5.0 when released as it improves on a lot of issues with v0.4.4. Cheers!
