Hi,
I was looking on these two examples (https://forums.ni.com/t5/Community-Example-Submissions/Measuring-RMS-Value-for-an-Analog-Input/ta-p/...) and (http://forums.ni.com/t5/Example-Programs/DAQmx-Acquire-with-Multiple-Channel-Input-Ranges/ta-p/34911...) as a help on how to create a multi-channel interface that individually show graphs and numeric values.
I made my interface, but I don't have an idea how to enable it to show every single graph and their respective numeric values. Any help?
Block diagram is made in LabVIEW 2016.

What exactly are you having trouble with? The Physical Channels input is where you would type in the channels that you will be reading in and then these channels will be output to your graph. What are you seeing, or not seeing? Are you getting any errors?
Cheers

If I'm interpreting your message correctly, there is a very simple answer, but I'd figure you'd already know this and wouldn't need to ask. Are you asking for an Index Array function on the array of waveforms to breakout the individual waveforms?

I need to get individual waveforms and numeric values (DC, RMS, peak-to-peak, +peak, -peak) for every single input, not all the inputs at the same waveform graph for example. I don't know how to achieve this.

Hi vedran,
you read an array of waveforms from your DAQ device: use an autoindexing loop on that array and calculate all values inside the loop on the individual waveforms!
I made my interface
This (the "autoindexing" part) is very basic LabVIEW stuff: did you notice the suggestions to learn LabVIEW given in the header of the LabVIEW forum?
As you talk about an "interface": please do those beginner tutorials. It really helps when you know the correct terms in LabVIEW like "block diagram"…
