I've just starting using the spectrogram function, but I can not get it to plot on a log scale for the frequency axis that mimics the plot generated by logy. Here's the basic spectrogram I am running: %%Wv is wave signal of the word shore ...

Does anyone know how to plot actual time interval in Spectrogram using STFT? I want to analyze an event in a signal in a certain time span, but using the spectrogram built in function plots in Spectrogram from 0, while I want it to be plotted from for exp. 5083s time span as seen ...
"plot(spectrogram(M(:,1)))" generates a plot whose y-axis values equal those of the x. The result is a set of lines that spiral outwards from a point in the center.If the function you are using is the MathWorks' version of spectrogram, then you are plotting a complex-valued function...

I know I need to wavelet transform the data using a morlet wavelet, but then I want to plot a spectrogram of the resulting signal and I don't know what I need from the wavelet transform to do so or what function to use to plot the spectrogram. Help is much appreciated!
