How to draw the dendrogram using AgglomerativeClustering operator?

xixirhwfy

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,
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:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.2.002">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.2.002" expanded="true" name="Process">
    <process expanded="true" height="251" width="413">
      <operator activated="true" class="retrieve" compatibility="5.2.002" expanded="true" height="60" name="Retrieve" width="90" x="110" y="157">
        <parameter key="repository_entry" value="//Samples/data/Iris"/>
      </operator>
      <operator activated="true" class="agglomerative_clustering" compatibility="5.2.002" expanded="true" height="76" name="Clustering" width="90" x="313" y="165"/>
      <connect from_op="Retrieve" from_port="output" to_op="Clustering" to_port="example set"/>
      <connect from_op="Clustering" from_port="cluster model" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

Best,
Nils
