ABSTRACT:
A method and apparatus for calibrating the scale of an X-Y display device is provided wherein at least two intersecting linear loci are formed and displayed on the screen of the device to show the X and Y axes of effective coordinates of the display device. The display of intersecting loci facilitates adjustments of the device enabling effective coordinates to be coincided with the coordinates of the scale.
