"Flatten clustering's centroid"

Remixman

We have the centroid plot view for visualize clustering centroid in k-means operator. But when use agglomerative + flatten cluster, I can't see the centroid. Are there any method to show flatten clustering's centroid.

Agglomerative cluster models don't work with the Extract Cluster Prototypes operator; it expects a centroid model. You would have to calculate them manually using the Aggregate operator.

Something like this

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.3.008">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.3.008" expanded="true" name="Process">
