The GridOn command enables a grid on the graph screen (you can disable it again with the [[TI-BASIC:Gridoff|GridOff]] command). How fine or coarse the grid is depends on the [[TI-BASIC:System_Variables#window|Xscl]] and [[TI-BASIC:System_Variables#window|Yscl]] variables. Drawing the grid just involves plotting points all the points of the form (A×Xscl, B×Yscl) that are in the graphing window.

= Advanced Uses =

GridOn can be used to shade the entire screen if Xscl and Yscl are small enough that the points on the grid are one pixel apart:

:ΔX→Xscl
:ΔY→Yscl
:GridOn

This is one of the shortest ways to shade the screen, although [[TI-BASIC:Shade|Shade(]] can be used for a (usually) even shorter way. However, using GridOn is also very slow: the fastest way involves the [[TI-BASIC:Horizontal|Horizontal]] or the [[TI-BASIC:Vertical|Vertical]] commands in a [[TI-BASIC:For|For(]] loop.

You could also use GridOn to draw the playing grid for a Dots and Boxes game.

= TI-84+CSE Grid Commands =

On TI-84+CSE version calculators, the GridOn command is replaced by two commands, GridDot and GridLine. GridDot does the same thing as the normal GridOn command, whereas GridLine draws a grid where all grid points are connected by solid lines. The two grid commands can also be used with color arguments.

:ClrDraw
:GridDot GREEN //Draws a dotted green grid
:GridOff
:GridLine 11 //Draws a red line grid
