Can I plot spectrogram with y-axis is frequency and x-axis is angle from goniometer related with the time?

Hi Experts, I recorded 2 signals which are acceleration signal and angle from goniometer with same sampling rate. So, they have a same length. Then, I try to plot spectrogram which it provide frequency and time from acceleration signal. After that, I would like to change X-axis as time to be angle which I got from goniometer, Can I perform it?

Thanks

You have to read about this: https://in.mathworks.com/help/signal/ref/spectrogram.html

I have read it and try with this way but it not work

Acc %%%Acceleration signal

Go %%%Goniometer signal

[y,f,t,p] = spectrogram( Acc,256,250,256,fs,'yaxis');

%%%Then,I try to plot it without using spectrogram command
 figure;surf(f,t,10*log10(abs(p')),'EdgeColor','none');
 axis xy; axis tight;colormap(jet); view(90,-90);

%%%Then,I try to change time to be angle with resample because t is changed from window calculating in spectrogram function

reGo=resample(Go,1670,10240);
 figure;surf(f,reGo,10*log10(abs(p')),'EdgeColor','none');
 axis xy; axis tight;colormap(jet); view(90,-90);

The two figures should be identical. But the results were two figures look different. Between the frequency and degree view over the spread than between the frequency and time.
