[yt-users] Power Spectrum

[Nathan Goldbaum]

Hi Tyler,

If you have a covering grid, it would probably be best to not use the yt plotting commands.  Instead, you should make your own plot with your favorite plotting system of choice.  Matplotlib is a nice pure-python solution and the pylab interface is very nice if you're familiar with matlab.

Cheers,

Nathan

I've tried using PlotCollection, but I get an 'unhashable type' error when I plug in my Fourier transformed data as one of the inputs to the add_profile_sphere command.  So how would I go about plotting this?  Is there an alternate way to use PlotCollection, or should I be using something else altogether?
