#34246 — Python Cluster

Dear Group,

I am trying to use the cluster module as,
>>> from cluster import *
>>> data = [12,34,23,32,46,96,13]
>>> cl = HierarchicalClustering(data, lambda x,y: abs(x-y))
>>> cl.getlevel(10)
[[96], [46], [12, 13, 23, 34, 32]]
>>> cl.getlevel(5)
[[96], [46], [12, 13], [23], [34, 32]]

but now I want to visualize it if any one suggest how may I use visualization(like matplotlib or pyplot etc.) to see the data?

Thanking in advance,
Regards,
Subhabrata.

No such module in the stdlib.

Start by showing what OS, what Python version, and what external
libraries you've installed and are using, and only then can you ask a
meaningful question.

You mean like a dendrogram?  Scipy has support for that.  It uses
matplotlib to do the actual plotting.

One option is to use a scatter plot with different color per cluster. See the many examples in http://matplotlib.org/gallery.html.

Thanks Miki. Good Gallery I think it'd do. We can plot as we feel. Regards,Subhabrata.
