Pulse width Measurement Using DMM

I am using NI PXIe 4080 for measuring pulse.I can be able to read the samples and I have plotted using waveform chart but pulse width I am unable to measure.Please suggest me to measure pulse width.Below I have attached my code.

You should base your code on one of the waveform-mode examples instead of a multi-point DMM measurement.  "Read & Graph Waveform.vi" might be a good choice.  It will give you a waveform that you can pass directly to "Pulse Measurements.vi"  (in the Waveform Measurements palette) to get the pulse width.

 

DMM-mode measurements do not contain timing information, whereas waveform-mode measurements do.

Sorry Sir, It was not solved my problem.One small information sir, I am reading samples from DMM and plotting in chart continuously samples w.r.t to amplitude.I got a VI transition measuremnts.vi by which i can be able to detect falling edge accurately but not rising edge so still i am working on it.Please suggest me if you have any other way.
