This should be straightforward, but as with so many things LV, I just can't seem to find the solution.
I am using a waveform chart to display waveform data type acquired via DAQmx with a reference trigger. I want to display the data relative to the reference trigger. That is, I want the reference trigger to be at t=0, and I want the rest of the data to be displayed using the waveform attributes t0 and delta t. I do not want to display absolute time. In other words, I want it to display much like an oscilloscope does.
I can elect to "Ignore Time Stamp" on the chart, but then the data is always interpreted as the first sample being t=0.
I would like the solution to be in the Display Format of the chart properties, but I suspect that I will have to use the number of pre-trigger samples and do some additional programming.
Much thanks,
Matt

Not easy to do as a waveform!
Convert to XY Pairs and subtract trigger time from X
