Claim One:
1. An apparatus for compressing a display of a waveform, the apparatus comprising: a compression interval memory containing data representative of a waveform over an interval to be compressed for display; an array of accumulating means with each accumulating means being associated with one or more pixels in a column of pixels, the column of pixels being associated with one quantum of a display pixel map; means for choosing pairs of points from the data in the compression interval memory; and means for converting the chosen pair of points into a weight value and a range of pixels to be affected, the weight value being a function of a number of pixels in the range of pixels to be affected, and for causing each accumulating means associated with the range of pixels to be affected to add the weight value to a previous value in memory to produce an accumulated value, the accumulated value defining a gradable visual characteristic.
