I'm using the 'psd' function to take the power spectral density of a waveform. Afterwards I can view the plot of the psd, however, I can't seem to find the data that is being plotted from the psd. I have the plot, but I can't find the x and y coordinates. I can't use ginput because there are 5000 data points.
I've done some searches both on this site and on the web and can't find anything on this. One would think that this would be a very commonly used feature. Yes, most of the time users plot data that they already have stored in variables, however, when performing complex functions that plot to a graph those variables aren't accessible (or are they?).
