Patent ID: 8049754

Claim:
A method waveform drawing on a display, comprising: generating a plurality of waveforms by a processor with certain waveforms being in the same space for eclipsing the waveforms in a rank order and storing a plurality of drawings points with the results of the eclipsing of the waveforms in rank order in art eclipsed list; performing a reduction of flicker on the display from the data outputted from the eclipsing of the waveforms in rank order, an erasure list mad a draw list including the results of the reduction of flicker; copying from the eclipsed list, to a predecessor list the predecessor list including drawing units representing vertical stripes at a given x-axis position after performing the reducing of flicker on the display; optimizing the erasure list from the data outputted from performing the reduction of flicker mad storing in an optimized erasure list; and drawing waveforms on the display including multiple waveforms in the same space according to at least one of the eclipsed list, erasure list, draw list, predecessor list and the optimized erasure list, wherein optimizing the erasure list further comprises copying drawing units from the erasure list to an optimized erase list, the optimized erase list including data where no erasure operates on any points contained in the draw list.
