graph - How to capture data from start to end

Hi Gerd,


I want the current time (the system time) on my graph(x axis). I want the system time to be synchronized with the readings. And I dont want all samples. Actually I will be adding a log loop later, which logs data every second. That's why I take average and get a single value every second. If I use waveforms, I will not be able to get the average.

Hi Gerd,

Hi kdm,



Don't you think you can try on your own before crying for help?


This vi too is not as what I wanted.

You should always state in clear and full description, what your goal is. When it's not what you wanted you can adapt it as you like…


I can display current (system) time nicely on a chart - when using waveforms as suggested before:


(I replaced your DAQmx stuff to create a working example VI…)

Best regards,
