Is there a way I can plot on top of the output spectrogram from using the 'stft' function?

I know you can use 'uistack' but I'm having trouble assigning the STFT to a variable as for 'uistack' you need something like:

uistack('h',top)

Where h is the plot.

At the end of my code I run:

stft(x,1000,'FFTLength',4096)

But in order to do 'uistack' I need to save this as a variable, however assigning a variable just outputs the values as opposed to the plot itself.

If I instead try:

[S, F, T] = stft(x,1000,'FFTLength',4096);

surf(s, f, t, 'edgecolor', 'none')

Then I'm told that for the function 'surf', s, f or t can't be complex. I get similar errors trying to use other types of plots as well.
