These are big files, typically 2-5MB with hundreds of columns in them and I worry about efficiency. I do know doing it the way I current do is very fast especially since the first time I read a file it gets cached and I'm on not sure what happens with 'cat'. I'd think the results do not get cached and would have to be regenerated for each line I want to plot. For some plots there can be as many as 16 lines. > > -mark > >>-----Original Message----- >>From: mar...@gm...
