Title: Ti-83+ Ti-Basic: Fastest Way to get the Graph Screen to redraw itself
Post by: Hot_Dog on December 16, 2010, 02:57:28 pm
Normally, if nothing has changed since the last time you graphed equations, displaying the graph screen will simply cause your graph to load instantly, there is no redrawing.

In Ti-Basic, something like "1->Y1" will cause DispGraph to redraw the entire graph.  But it's not the most optimized way.  Is there anything faster?  A cookie and a bag of peanuts goes to the helpful person who gives me the fastest, most optimized command to force a graph redraw upon reaching the command DispGraph.

Thanks, everyone!

I got:
Code: [Select]
Connected
DispGraph
EDIT: This command alone will always display and redraw the graph screen:
Code: [Select]
ZoomSto

Runer112, ZoomSto is quite useful, thanks a lot!  There's something called a regraph hook I want to use, and it only gets called when the graph redraws itself.  So ZoomSto is the best one yet!

Well depending on what is being used you can also just call any of the window adjusting commands and that will force redraw it too. So unless your graphics rely on the coordinates you could use those too.

ClrDraw is also an option.

Code: [Select]
:ClrDraw
:DispGraph
