I'm looking to produce plots from some very large data sets. To start I've got a data set with 40 different series in it, each with 5000 samples that I'd like to produce a line chart out of, with each series represented by a line in the plot.
Numbers chokes after about 450 samples. Excel fares a little better and gets to 1000 samples. But neither of them can handle the full set of samples across all the series.
Something with an easier learning curve is preferred (i.e. I'm avoiding gnuplot like the plague until it's clear it's my only hope...) and it doesn't bother me if the generation of the plot can't be done in real time. I don't mind setting things up and then waiting for an image of the plot to be produced in the background. Bonus points if it can produce plot output that's as easy on the eyes as Numbers will produce for smaller data sets.
