Waveform Graph and saving the X-Axis Offset

[Adam Hicks]

Hello All.

I am using LabVIEW as a controller for an external Pulser/Receiver. Using my LabVIEW GUI, commands are sent (such as the Trigger Delay) to the Pulser. when I gather my data from the receiver, it is in the form on a 1-D array. I have set everything up so that the signal appears on the front end properly, setting the X-axis offset on my waveform graph to correspond to the trigger delay I gave the Receiver. However, the background data remains unchanges and always starts at time 0. Is there a way to modify the waveform data to make it start at the trigger time instead of Zero?

My issue is that, while my front end displays all of the information correctly, when I save my wavefrom graph, the X-axis always starts at 0.

Thanks,

Adam

You can use Build Waveform Components Function and bundle in a new t0 value.

That did it.

I had tried that solution before, but discarded it because I did not actually save the data when testing it, but rather just looked at the probe data. The probe data, which I find misleading, does not obviously indicate the change that occurs to the saved data. Per your suggesting I re-tried funneling my trigger time in as t0 when building my waveform and it fixed it right up when looking at the saved data.

Thanks again,

Adam
