A waveform drawing routine is disclosed that includes receiving an array of predecessor image data points, wherein the predecessor image data points form a predecessor line that has a predecessor high end point and a predecessor low end point, receiving an array of successor image data points, wherein the successor image data points form a successor line having a successor high end point and a successor low end point, comparing the successor line to the predecessor line, and maintaining any portions of the predecessor line on a display that intersect with the successor line. The method described above for drawing each line segment that forms the waveform is repeated until a complete waveform is drawn on the display that consists of the concatenation of these individual lines.
