How to draw the dendrogram using AgglomerativeClustering operator?
Hello,everyone!
It's my first time to use Rapidminer, and I got problems drawing the dendrogram using AgglomerativeClustering operator. The "dendogram" field in the Result Perspective is empty. I'm sure my previous steps are correct and the result is correct, but I need also the dendrogram. I found a java script in the source file named "Dendrogram plotter",but I don't know how to use it. It's not in the operator. Do I need to import it the the AgglomerativeClustering? Is there any other way?
Thanks for answering!

Hi，Nils!
Thanks for helping! But when I use the default parameters of the AgglomerativeClustering operator, the dendrogram can show out too. But when I changed the parameter, for example, my tables are all integer numbers, and I have to use Jaccard Similarity to calculate the distance. In my table, the first colomn is the "id", and the other colomns are either 0 or 1. The "Graph View" in Result Perspective is correct,but the dendrogram field is empty. Here is my XML code:

Hi,
unfortunately i haven't got the data you are trying to load. If I plug in the iris data instead the dendogram is shown.
Would it be possible to provide a short .csv file with data equal to yours and a process that reproduces the missing dendogram?

Best,Nils
can you please post a example process according to http://rapid-i.com/rapidforum/index.php/topic,4782.0.html ?
With this short process everything works fine: Best,
