How do you plot the number of clusters vs the percentage of variance explained in RapidMiner?

I wish to learn to this quickly in a free miner if the need arises without R or Python. The closest thing I found: http://community.rapidminer.com/t5/RapidMiner-Studio/Elbow-Criterion/td-p/20612 , but it only states the average within cluster distance and the DB-index.

Hi Julio,

 

i only know % of Variance covered from PCA, not from clustering algorithms. Could you eloberate a bit on what this value should be?

To be honest i can only imagine that something with Variance makes sense with euclidian based clustering, right?
