How to change x,y origin of canvas to bottom left and flip the y coordinates?

I have a bunch of data points that I would like to two-way bind to points on a canvas.

I'd probably create a custom panel instead of using Canvas and give it the attached properties that make sense for your needs. Here is an example of implementing a custom panel:

Something like Canvas is very simple since you don't have to do much in the measure and arrange overrides.

You may also be able to inherit from Canvas and override ArrangeOverride, I haven't tried that but it may work.
