Campbell-Graph for Engine-RunUp

Hello,

 

we want to write a VI to analyze an engine run-up and display the spectrum in a Campbell-Graph, or Colour-Map in Labview 2009.

We got two Signals (Engine Revolution and Motor Sound), merge them with the VI Spectral-Map and send them to the Colour-Map Graph.

It all works to that point, but the Graph does not keep the data when the program is running.

 

Does anyone know a solution to that? Or another way (or VI) to visualize this matter?

We are Labview-Newbies, so we know our problem is probably not so hard to solve, we just do not know how.

 

Thank you very much!

Hi josh,

 

graphs only display the data wired to them…

 

When you want to keep a history (like a chart does on it's own) you need to create an array holding these history data!

Best regards,
