Hello Paul, Just a couple of thoughts as you continue to investigate your program. Your DAQ data may be gathered as a waveform data type, which combines data with timestamp information. If that is the case, you must extract just the data and ignore the timestamp if you are to plot data from different time periods on the same x-axis. So, you might wish to extract the data using the "Get Waveform Components" function found in the Functions >> Waveform palette. This will allow you to return just the array of data rather than the timestamped waveform. Then, you can analyze that array to see how many data points are being generated at once, etc. After you know that, you can implement a programming structure similar to mine because you will know how many times to call your DAQ code in order to generate the number of data points you want at a time (such as 100).
If you'd like, post a screenshot of your code (or the code itself) and I'd be happy to help you sort through the DAQ programming, which sounds like the main stumbling block at this point. Hope this helps! Liz F National Instruments
