Original ticket http://projects.scipy.org/scipy/ticket/798 on 2008-11-26 by trac user damian.eads, assigned to trac user damian.eads.
Brian Clowers of PNL suggests a new keyword argument for the dendrogram function of the scipy.cluster.hierarchy module. Specifically, allowing a custom axis to be specified so that dendrogram plots can be sent to a PyQt (or PyGTK) GUI component instead of pylab.
ENH: add axis keyword to dendrogram function
This fixes gh-1325 (Trac #798). It allows scipy dendrograms to easily be
plotted on custom axes, e.g. as part of a larger figure. It does not import
pylab at all if an axis is provided, which is useful for those who are using
the matplotlib API.
