Screen limits

You can set the screen limits  so that you can make a graph of any size . For example, enter GR SC 150 600 150 600 to make a square graph. The screen limits are in Tektronix screen coordinates. The x range of the screen is 0 to 1023, the y range is 0 to 780. Remember to leave some room for the axes labels.

Tick marks

You can have the tick marks  drawn on the inside of the graph instead of on the outside.

Grid lines

You can have grid lines  drawn at the tick marks.

Color

You can specify the color of the grid.
