How to set the GoTo Vars X and Y?

[DrD]

In the Advanced Graphing app, from a program or the command line, is there a way to set the Go To Vars X and Y?
For example, with the Advanced Graphing app as the current app, setting X:=any real number, does NOT change the X value in the Plot | Menu | Go To | X value. It seems to be a different instance of the variable X. Perhaps, it can't be accessed?

Looking for something like this (doesn't work):

Code:


N:=2;
EXPR("Advanced_Graphing.Go_To.X:=" + 'N');

Thanks,
