I want to customise a figure legend by reversing the horizontal order of the symbols and labels. Example: change x data1 to data1 x. In Gnuplot, this is simply achieved by set key reverse.

In matplotlib, there seems to be no user-friendly solution, or no solution at all. I've found examples how to reverse the vertical order, but no means to move the symbols (handles) to the right of the labels.

As a low level solution, I thought about changing a kind of handle anchor or just shifting the handle's position, but couldn't even find an entry point for that.
