As long as your spectrums have the same number of points as well as the same dx and X0 this should be simple. Take a look at the VI below. It simulates 3 signals and display them on a waveform graph. I added a picture of the code in case you don't have labview 8. The code simply builds a 2D-array from 3 1D-arrays and bundles them into a cluster together wit dx and X0. The order should be: 1) dx 2) X0 3)Array counted from top.

ooops, a little typo sneaked into my reply. The order of elements in the cluster should be:
