When I use the Powergui FFT Analysis Tool (in the matlab 2019a), I find it can'work. In the module of "Available signals","Name" and "Input" are always "Empty", though I have selected “Log data to workspace” and "structure with time".Are there any other parameters to set?2.PNG

You are not logging the data into workspace see the image what you have attached. Name and input is empty.
I had logged the data into workspace, but it didn't work.捕获.PNG

I met the same trouble as yours! I found in old vesion things are not so complex. What they did in upgrade?
btw, are you also a student doing a physical experiment?

I find a way to solve this! You have to click the button I circled and it will display these options. Cancel the single simulation output and you can get your data after run!
非常感谢,方法很有用。但是我不是物理实验的,而是做电力电子实验的时候用到它的。
This worked!! 100%
Thanking you. I wasted four hours and later saw your thread and the problem solved in four seconds.

Try this methods
1.Try to log the data into workspace otherwise.
2.This FFT window will work only after the successfull running of your model
3. Close the simulink model once and run it again
