Casio Graphical Calculator Encyclopaedia

`Token:`	`PlotOff`
`Type:`	`IO function`
`Usage:`	[Orange \|Green ]PlotOff <x>, <y>

`Definition:`

Clears the pixel at position <x>, <y> relative to the graph axes. If either Orange or Green are specified, there will be no difference to the result but it will not cause an error.

`Other information:`

This is one of the Plot... commands, which plot points relative to the current graph axes rather than acting directly on the graphics screen as the Pxl... commands do. If the standard range ('Range 1, 127, 0, 1, 63, 0') is being used, the same pixel could also be coloured using the command 'PxlOn 64-<y>, <x>'. Notice that the horizontal and vertical co-ordinates are referred to in the opposite order, and that the vertical co-ordinate is measured in the opposite direction. Using the range 'Range 1, 127, 0, 63, 1, 0' will give axes which are measured from the top down so that it is only necessary to swap the order of the co-ordinates when changing between axes-based and screen-based commands.

Unlike the Plot command, this command cannot be followed by a display triangle (_) to allow direct pixel editing.
