Hi,
I simulate a bipolar SPWM in simulink of matlab2019a. I want to get it's harmonic spectrum. After runing the simulation I change formt of variable from this path: Scope-> Settings -> logging -> log data to workspace -> Name the desired variable -> change the format to 'Structure with Time'. I open the fft anlysis tool from powergui block but there is empty signal. Can anybody help me with this problem?

Go to Configuration Parameters, on "Data Import/Export" Section, uncheck the "Single simulation output" box.
It worked for me and am using R2019b
