I came ready to hate with bias because I often don't like wrappers, but at least the .format seems like an objective improvement.
But I never understood why matplotlib insists on ax, fig and that's still in there...
Directly working with matplotlib classes tends to be more clear and concise than pyplot, makes things easier when working with multiple figures and axes, and is certainly more “pythonic”.
I disagree.
Looks like a solid project overall! Thanks for your effort!
