Combine waveform chart and waveform graph

[ishmael]

I would like to combine the properties of waveform charts and waveform graphs, i.e. I'd like both continuously changing and fixed graphs at the same time.  Specifically, I would like to display one waveform as a fixed, unchanging background, then display another waveform on top of this background while my code is running, as data arrives from a DAQ, point by point.  Is this possible?  Thanks!

The answer is to use XYGraph.  See attached example.
