Well, technically, legend never grows. Whenever you call legend(), a new legend instance is created and the old one is just destroyed. Anyhow, as far as I can tell, the (x,y) coordinates given to the *loc* parameter has been the coordinate of the lower left corner of the legend (but I don't think this is clearly specified in the documentation). Therefore, I don't think it is a good idea to make the legend grow(?) downward while you're supplying a fixed coordinate of the lower left corner. This is hardly possible and it seems to make little sense to me. Anyhow, I just submitted a patch to the svn that add an optional *bbox_to_anchor* argument for the legend class. This lets you specify the bbox that the legend will be anchored (the default is the bbox of the parent). For example, legend(loc="upper left", bbox_to_anchor=[0.0, 0.5]) will create an legend with its upper left corner at (0.0, 0.5), and it will grow downward. Note that when len(bbox_to_anchor)==2, a bbox with zero width and zero height is created. I hope this suits your need. -JJ ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
