patternplotting - java

Question

hi,

if we have 3 metrics ( attributes/vallues ) for 10 people (just an example). is it possible to find a pattern for the 10 people based on these 3 metrics and plot them? I am looking for doing this pattern matching in java. is there any library which can help me to do this in java??? The goal is to find different patterns which exist based on their values( the metrics).

Thank you.
