"Cluster visualization problems"

Hey,

first of all I want to say sorry for my english (I'm from Germany).

My problem is (like the topic said) the visualization of the cluster i got from Rapidminer.
What i want to do is to cluster some data I got from my prof.
I used the W-XMeans clustering to cluster the data and got 2 clusters.
Now I want to see where the centroids of these clusters are but the file created by the output of W-XMeans -O is empty.
Also I want to inspect the boarders of the center and the distance between the data I used.
I allready tried some I/O-Atrributes but it doesn't work. :-[

Hope someone can help me.
Thanks Xeixes

    Hi,
    actually it's pretty easy if you use K-Means instead of this cryptic Weka operator: When the Cluster Model is shown in the result view, you can see the centroids. Or you can use the operator Extract Cluster Prototypes to get the Centroids as an example set.

    Hey,

    thanks for your help.
    I used K-Means and was able to see the cluster centroids and where the algorithm divides the clusters.
    The operator Extract Cluster Model doesn't really help because I use rapidminer 4.5 where it is not containt.

    Greetings, Xeixes
