plot graph with peaks mraked

[sukhiray]

I am reading a signal through DAQ and then want to plot it indicating its peaks. The Waveform Peak Detection VI helps to get all the information about peaks, but how to plot a graph of the signal with peaks pointed in it? Can the X value of each peak also be marked?

Is below kind of what you are looking for? I jut took the array of locations and indexed it for as many peaks as I knew I would have (you would have to change this if you plan to have more peaks) Then wired the output of the indexed array to a property node for the Xvalue of a cursor.

Again, you are going to need as many cursors as peaks.

Hope this helps!

I already have a singal saved in .lvm file. I have to plot this signal only along with its average in the same window. The peaks will be detected in the averaged graph and will be marked there with their X-axis values.

this much I have done. now how to send this location information to the property node of graph? there is a data type mismatch problem.

Please help me.
