[Iddo Keret]

hi all,
i'm student at department of electrical and electronic engineering.
in my studies  i  have to analyze  experimental results 
the graph is only 2  variables but there is a  lot of data (some thousand numbers)
does somebody know the tools exist today for blinds to amalyse graphs?
maybe there is a  tuch surface or a  method to "hear" and understand the graph ? 
does someone have  experience whith this as a  scientist or  a  student at scientific area ?
any information or suggestion will be appreciate
