PSP Grapher, come dice il nome stesso, permette di visualizzare dei grafici delle funzioni che inserite secondo la sintassi y = a*(x^3) + b*(x^2) + c*(x) + d
Nella versione 0.02 è stata implementata la capacità di calcolare anche gli assi translati semplicemente rispetto alla variabile X.
Di seguito il readme ed in allegato il programma:

***UPDATE***: The bug he fixed was that you couldn't control the x-axis position. So he quickly modified it to include the x variable to select how much is added or subtracted from x.

Here is my new lua program for graphing on the PSP

The equation is as follows: y = a*(x^3) + b*(x^2) + c*(x) + d

================================================== ===

To scroll through which variable you are changing (a, b, c, or d) press L and R

Once you have the variable you want to change selected press up to increase the value by 1, down to decrease by 1, right to increase by
0.05 and left to decrease by 0.05.

Press Start to graph

Press Select to save a screenshot

Press Triangle to set a, b, c, and d back to 0
