RE: CSS BOY XY Graph

Yes, it is possible if you set buffer size to .NORD value and "Concatenate Data" to false. It will cut the waveform length to the buffer size.

Thanks,

OK. I got the XY graph to work (I needed to adjust trace buffer size).

At present the graph retrieves and plots .NELM values from the waveform. Is it possible to make it retrieve and plot .NORD values (or some other number of points) from waveform instead?
