I don’t understand exactly waht you want, but the spectrogram function (Signal Processing Toolbox) will do time-frequency analyses and plots.

If you have the Signal Processing Toolbox
doc spectrogram
There are numerous arguments to the function, but they will depend on your data and how you want to bias the time resolution vs frequency resolution with windowing and overlapping, etc
