From there, we can figure out where the key dendrogram() function should live, but at least your work will get in the repository as soon as possible. -Andrew - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

That was about 2 weeks ago, and the previous version was about 6 weeks old, at that point.

Glad you wrote this, I was about to. I noticed them only recently, and they're driving me nuts. They aren't just corners, they have to do with the overlap of two lines and Agg messing something up when thick lines overlap. Here's an example that illustrates it more easily (that's how I ran into it): import numpy as N from pylab import figure, show t = N.linspace(-1.0, 1.0, 2001) s = N.exp(-300*N.abs(t)) fig = figure() ax = fig.add_subplot(111) ax.plot(t, s, '-', lw=2) show() ### Plot this, then click on the little zoom tool (the cross) and do a horizontal right-mouse motion to widen/tighten the exponential. You'll see the white artifact move across the region of overlap of the vertical lines. Fortunately for me, the generated EPS don't have the problem (it's a pure Agg bug), so I'm OK for the final output. But it's really annoying on screen. My plots have tons of nearly retracing lines on them, and they look atrociously bad now.
