matplotlib-devel Mailing List for matplotlib

Hi all,
	We have updated the OSX binaries which include all dependencies in a
single installer (i.e. libpng, freetype, numarray, Numeric, ...).  There
are 10.3/panther and 10.4/tiger binaries which include mpl-0.80 and
basemap-0.4.2.  The panther binary includes wxpython and the tiger
binary uses the system included wxpython.  Please feel free to contact
me if you experience any problems.

I do - but for flexibility how about this patch which allows both
options? The kind of list intersection I've used isn't the most
efficient but as mpl isn't at its most efficient with large numbers of
artists I didn't think that would be a problem.

Hi Nick,

Although using a function may be the most general way of making
picking selective, I wonder if it is the most intuitive.  I suspect
that 9 time out of 10, a user will just want to pass a list of objects
on which to pick.  Do you agree?

Hi,

There have been several times when I've come across conditions where I
want a user to be able to pick from amongst a limited number of objects
on plots containing lots of other objects.  Previously I've written my
own functions to do this but it occurs to me that this is likely to be
something others will want to do.  To this end I've made a very simple
addition to the Axes.pick method to take a keyword argument test which,
if a callable, is used to filter the objects from which to pick.  A
patch to CVS containing the alteration is enclosed.
