Thanks very much for your help.

1. I download the vibrationdata GUI package of scripts written by Tom Irvine, I pick the Waterfall FFT and Spectrogram and pick begin analysis, after that I try to figure out how could I get the spectrogram plot for a very long time. But I failed to find out a way, Could you please give me some advice or suggestion? If you could, could you please just show me an easy example?


Thanks very much
