specgram internally computed the spectrogram and then displays it into a AxesImage instance (the im output argument). You can limit the range of values the colormap extends by passing extra arguments to specgram that are internally passed to the AxesImage.imshow method: See Argument "kwargs" in http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.specgram and http://matplotlib.sourceforge.net/api/axes_api.html#matplotlib.axes.Axes.imshow >>> Pxx, freqs, bins, im = specgram(x, NFFT=1024, Fs=fs, window=win, noverlap=2, vmin=-120) -- Fabrice Silva ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
