The Pt-On( command is used to draw a point on the graph screen at the given (X,Y) coordinates. Pt-On( is affected by the window settings Xmin, Xmax, Ymin, and Ymax. Make sure to change these accordingly when using it in a program, otherwise, you don't know where the point will show up.
Advanced Uses
The Pt-On( command has an optional third argument that determines the shape of the point (its mark). The mark can be either 1 (dot), 2 (3x3 box), or 3 (3x3 cross). Note that by using the 3x3 shapes the X,Y coordinates 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 or 3 will be treated as the default of 1. Remember to use the same mark when turning a point off as you used to turn it on.
