I was hoping there was a simpler way to display elapsed time next to the recorded data to confirm the sample rate and dt. 

 


You are using computer time to determine elapsed time. That is not accurate, especially for Windows. The clock in your DAQ is way better than the clock in the computer. If you want to confirm your sample rate, you need to use a frequency standard that is rated better than your DAQ. Your DAQ is probably 50-100 PPM accuracy. Measure your frequency standard and see if your DAQ measures the expected frequency.

Below is a quick mod to get elapsed time on the plot. I only did it for ONE plot, you need to change the properties in the other plots for relative time on the X-Axis. See if you can figure it out.
