waterfall plot in vibration test

[pengzqbaal1233]

Dear Friends,

I tried to use waterfall graph in Sound and Vibration Assistant Kit to moniter my signal peak shift when test enviorment is vibrating. The device I was using already got a DLL integrated function from vender which would output two 1D arrays as intensity and wavelength each while loop. I wanted to plot wavelength as X-axis, intensity as Y-axis and time as Z-axis. However, SVX Buffer Waterfall Graph doesn't seem like to accept the array of X-axis value. It only accepts x0 initial value and dx interval value. Could anyone tell me how to do this plot?

Hello pengzqbaal1233

Actually LabVIEW has a lot of examples in this case if you go to Help>>Find Example select the Search tab and put Waterfall click Search and you should be able to see different examples that use that VI. If you need you can modify those example for your application.
