Hello. Im using LabVIEW 2013 with myRIO 1900. I need to know how i can write a tdms file with two parameters. Ive converted my data into waveform using DDT and then wired it into the TDMS write. When i open the file all i get is the sensor readings. I need to know how i can show variation of my sensor input with time or input coming in from any other channel.
Thanks in advance.

waveforms only have one timestamp and a delta, which means in waveforms each datapoint is delta-time later than the previous one .. in other words the difference between two datapoints is uniform
since my own measurements are with varying deltas, i have my tdms with a timestamp channel and seperate data channels, so for every data entry there is a corresponding timestamp.
depending on your volume of data stored in tdms it might help doing that yourself
