Abstract
An apparatus for displaying ordinate-abscissa value pairs with discrete display points in the abscissa and ordinate directions determines an interpolated ordinate value at half the abscissa spacing between the respective abscissa value and the respective abscissa value of the display points to the left and right. A maximum ordinate value and a minimum ordinate value are then determined from the ordinate value of the respective ordinate-abscissa value pair, and the respectively interpolated ordinate values on the left and right. A random or pseudo-random ordinate value is then selected between the determined maximum and minimum ordinate values for every abscissa value of the display points. The ordinate resolution of the display points is thus reduced by comparison with the ordinate resolution of the ordinate-abscissa value pairs.
