You need to save data using a Scope block, ensuring that the data is formatted as a "Structure with Time". Search this documentation page for "History pane" and you'll see how to do this.
Once you've run this model and the scope data gets saved to the workspace, you should see it in the powergui block's FFT tool. You can then follow the steps as shown here.

dear sir,
actually my program is written in .m file (script file). how sir, i display it in scope?
i have variable which stores values of voltages with harmonics like
optimumv = 92.1596 -1.3810 -1.1094 2.7546 -0.2628
1st=92.1596
5th harmonic=-1.3810
7th harmonic=-1.1094
11th harmonic=2.7546
13th harmonic=-0.2628
i want to apply fft on above data. is this possible sir, i want a view of output as attached?
