I took into account the what DFGray proposed ... and here result(see attachment file).
And it's not bad working,but not excellent.

borovsk,
Sorry it's taking me so long to respond back to you. Why are you interpolating the data? It would be preferable if you were to attach the code you used for http://forums.ni.com/t5/LabVIEW/STFT-spectrogram/m-p/1750644#M611741, as your actual code is too cumbersome to read through. We need to take a step back and isolate just plotting the period of your waveformsH

Jason L,
I interpolating data, because I don't known how create irregularry axis Y on Intensity Graph. I attached old vi(1. invers array,
2. setting Y scale).

borovsk,
Thanks for attaching the code. It seems like when you reverse the array, the data reflects itself over the center of the Y scale. You can't just simply reverse the array and expect it to be the period, remember that the period is (1/frequency) which is not a linear relationship. Using this method, you would need to take the Y position of the frequency point and put it in the Y position that is it's reciprical.

You said:

You could help to implement it? I don't known how it will look.
