Hello RJP,
Here is an example program that shows the best method I've found to do this. Basically what I did is I changed the DAQmx Read to be an array instead of a waveform. This will make the waveform chart graph the y values vs. array index. Then I used a chart property node to at a scaling factor to the x-axis with the Multiplier property. I scaled the sample number by 1/rate so that it would graph time correctly.
I hope this helps, and have a good night.
