Nothing new here... just a small tool i made to plot procedural functions. Sometimes i need to analyse those things and Scratch is a cheap and easy way to do it. You have 4 different buffers to use where you can put your data in, then you can use UP, DOWN, LEFT, RIGHT to navigate the plots A, Z control the scale of plot 1 S, X plot 2, D, C plot 3 and F, V plot 4 Maybe only I find this useful, but why prohibit you from using it? lol
