You have several options. You can use a chart and send it a succession of waveforms that are timestamped. The waveforms are themselves evenly sampled, but their initial timestamps don't need to be. The option, and probably the one I'd go with is to use an XY graph. The X is a timestamp, and the Y is an amplitude. Make an array of timestamped amplitudes and update it with 10sec segments.
