Configurable Plot Axis Notation

[CallMeMSL]

Hello,

im currently using egui to write a visualisation for complex fourier transformations. I really love working with it, especially with the excellent plotting module. The only option that I'm missing so far is a way to modify the numbers along along the axes.

E. g. since I'm worling with complex numbers, I would like to display 1i instead of just 1. I'm also writing a module for svg parsing and plotting. Since svg paths are defined in matrix notation, this could also also be useful for inverting the y-axis.
I believe this would also be really nice for interactive web plotting Physics/Chemistry experiments where a unit on the axis is good practice.

Keep up the great work,
David
