How to make waveform graph plot. signal vs. time?

[Perfluorine]

Hello. I just started using LabView.

My problem is: how do I go from the digital signal (in the form of a string value) to its plot using waveform graph. My eventual goal is to monitor signal vs. time?

Thanks,

Tony

Hi Tony,

Where are you getting your digital string from?  What exactly is the format of the digital string.  What you will probably want to do is turn the string into an array and then use the Build Waveform VI to build up a waveform of your data.  Waveforms have three components:  the array of data (Y), a starting time (t0), and the change in time between samples (dt).  You can then write your array to the Digital Waveform Graph.

Hope this helps,
