Share My Creation Mathplotter

A simple math formula plotter but it is much harder than I thought for implementation...
The calc within Windows is a very nice graphic calculator but I don't know why it can't plot tan(x).
I found several math expression evaluation libs in the forum then tried them also stevel's mouse wheel snippet for zoom.
It seems 6 of formulas almost reach the performance limit with obvious dragging delay in full screen.

Are there any interesting/eye catching formulas for plotting? I guess It is less fun than scatter kind of plots.

Try: java -jar MathPlotter.jar (java version "1.8.0_202", bugs warning)

Reminds me of my own graphic calculator from 2003: http://www.mobyware.org/symbol-mc90...graphics-tag/graphiccalc-download-155506.html
This is actually the "grandfather" of B4X.

It had a nice feature of drawing the integral and derivative functions as well.

Erel, I checked the link and found it is for Window CE or mobile. Unbelievable that's already 20 years ago!
In my opinion without UI/UX designers mind involved in coding Windows CE is tragically out, I am glad B4X changes swiftly from CE to new era!
