Even better if someone can suggest a better graphical/visualization/plot option to display these two multivariate datasets so that the differences are conspicuous enough. With line graphs the visualization is not clear enough because the same values overlap on top of each other.

Dear Jim,

Thanks a lot for your helpful comments. I have never used WIDGET_TABLE function before since I am quite new to IDL Programming. The idea seems interesting and I want to try it. I am right now looking at the help page http://www.exelisvis.com/docs/WIDGET_TABLE.html
Do you know whether this function allows automatic addition of cell colours based on the range of values present or do I need to manually assign cell colours to the values? Additionally, if I assign colours to the cells which hold the values, will the values be still visible or I can replace the values just with colours? Apologies if I am asking some basic questions which may be otherwise common knowledge among the IDL Programmers' community. It would be a great help if I can find an example. I will search the web for it. If you have any other suggestions they are welcome.

James
