meaning of documentation line.. for obspy.imaging.spectrogram.spectogram

Question

My apologies, - I think its probably a very basic matplotlib-related question, but I'm still a newbie sorry.

In the online documentation of obspy.imaging.spectrogram.spectrogram

http://svn.geophysik.uni-muenchen.de/obspy/docs/packages/auto/obspy.imaging.spectrogram.spectrogram.html#obspy.imaging.spectrogram.spectrogram

... on the "axis" option the documentation says '' "Plot into given axis, this deactivates the format and outfile option" ''

Could you possibly give me a very simple example of how I would define "a given axis",

e.g. for your same example as in the ObsPy tutorial, but instead using a new y-axis constrained to frequencies 0.1 --> 15 Hz ; and perhaps with an output file name "test-spec.png" ?

( I can already do the unconstrained version, using for example :

'' spectrogram( t5.data, df2, wlen=60., outfile=outfilename, format='png', log=True, title=plottitle) ''

but I need to constrain the y-axis a bit... )

Thanks very much !

megies imaging: - adding a kwarg show (default: True) to control if a spectrogram plot pops up immediately or not - setting show=False allows further manipulations to the plot, at the end just call plt.show() manually - see #180 - no changes in behavior for old code
