void cmd_zoomin (void);

Executes TI-Basic 'ZoomMin' command.

cmd_zoomin displays the Graph Screen, lets the user set a center point for a zoom in, and updates the viewing window. The magnitude of the zoom depends on the TI-Basic system variables "xFact" and "yFact", which determine the zoom factors. In 3D Graph mode, the magnitude depends on the system variables "xFact", "yFact", and "zFact". See the TI-Basic manual for more info.
