We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope. |

The Pt-Off( command is used to turn off a point (a pixel on the screen) on the graph screen at the given (X,Y) coordinates. Pt-Off( is affected by the window settings, which means you have to change the window settings accordingly, otherwise the point won't show up correctly on the screen.
Advanced Uses
The Pt-Off( command has an optional third argument that determines the shape of the point (its mark). The mark can be 1 (dot), 2 (3x3 box), 3 (3x3 cross), 6 (3x3 box), or 7 (3x3 cross). Note that by using the 3x3 shapes the X,Y coördinates will be the center of the shape and not the upperleft corner of the shape. You don't need to specify the mark when using the first mark because it is the default; also, any value that isn't 2, 3, 6, or 7 will be treated as the default of 1.
