Checkout out Artist.findobj http://matplotlib.sourceforge.net/api/artist_api.html#matplotlib.artist.Artist.findobj Artist is the base class for everything in a matplotlib figure, the Figure, Axes, Axis, Text, Line2D, Polygon, etc, all derive from Artist, so you can call this method on any mpl object to recursively search for objects of a given type. By recursive, I mean search the objects children, their children, etc. See also http://matplotlib.sourceforge.net/users/artists.html for more info on the artist hierarchy. But for your specific example, each axes has an `images` attribute, which is a list of images it contains (this is detailed in the artist tutorial linked above, so you could simplify your code with something like: images = np.concatenate([ax.images for ax in fig.axes]) JDH ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more. Splunk takes this data and makes sense of it. Business sense. IT sense.
