Hello, I've got a spectrogram figure, obtained with the Matching Pursuit Tool Kit. The color represents the intensity of each frequency. I would like to get the time/frequency data, in order to build a matrix with the columns containing the information for each frequency the rows containing the information over time. The figure is a patch object. Thanks.
