When the instruction is executed, the TI-82 STATS stores the
value to the window variable and displays the value.
The variables @X and @Y (items 8 and 9 on the VARS
(1:Window) X/Y secondary menu) define the distance from the
center of one pixel to the center of any adjacent pixel on a graph
(graphing accuracy).
@X and @Y are calculated from Xmin,
Xmax, Ymin, and Ymax when you display a graph.
@X =
(Xmax N Xmin)
94
@Y =
(Ymax N Ymin)
62
You can store values to @X and @Y. If you do, Xmax and Ymax
are calculated from @X, Xmin, @Y, and Ymin.
