I am trying to make a program for my calculator (TI-89 Titanium if that helps) that takes a function from user input and graphs it on the left side of the screen. Then it will apply a transformation to the function and graph it on the right side of the screen. The reason I think this is possible is because you can split the screen with setMode("Split Screen","LEFT-RIGHT") and then setMode("Split 1 App,"Graph") and setMode("Split 2 App,"Graph"). I also used setMode("Number of Graphs,"2") before that because I was getting an error if I didn't. I can then graph stuff with DrawFunc "", but it only goes onto one of the graphs. I can't figure out how to switch which graph I am drawing onto. I tried searching this and reading the documentation, but I couldn't find anything about it.
My Code:
program()
Prgm
StoGDB gdb1
setMode("Split Screen","LEFT-RIGHT")
setMode("Number of Graphs,"2")
setMode("Split 1 App,"Graph")
setMode("Split 2 App,"Graph")
ClrDraw
ZoomStd
ZoomSqr
DrawFunc 5*x^2-2
Pause
RclGDB gdb1
setMode("Split Screen","FULL")
EndPrgm
Good news! I figured out how to do it after a long time... I just had to use the switch() function in order to switch which window I was calling the functions on.
