representation of the cascading spectrum

Solved!

Hello,

 

I have vibration datas and the associate spectrum.

I'd like to represent STFT (cascading spretrum) like in this picture below. 

Please any suggestions to do this ?

 

thanks in advance!

You could use the 3D Plot functions, but it will look like a LabVIEW 3D Plot ...  [There is a recent discussion on the Forum where I commented on creating a 3D Plot, within the last 10 days ...].

Hi,

Thanks for your replies.

 

How could I build it from some vibration datas ?

Very nice.  Why don't you return the favor of the help we gave you by attaching an actual VI so that an interested user could download it, run it, see what it does, and adopt it for their own use?  Please attach your VI.

Thanks you!

 

These are the block diagram and the front panel below!

You can change every constants by controls and replace signal1, signal2, signal3 by every kind of signal (ex:vibration signal in my case) to have waterfall spectrum, also call STFT (short time fourier transformer). You can change the number of spectra in the waterfall and set intercall between every spectra.

 

Regards, 

Fred.
