Hey guys, So I'm trying to make a graph from data I have in an excel spreadsheet. It's from a Differential Equations extra credit assignment from last year, but I was curious to see how the data looked graphed (I know the general shape, but still curious, I like numbers and graphs ). Basically, Excel 2011 can't graph it. I think 255 lines is the max? Either way, it runs at 100% and goes to 1.82GB used before it crashes, if you try to graph it. So basically, I need/want a graphing program that can actually graph the data. Any ideas? TL;DR 54938 lines of data, I need to make a graph and Excel won't work. Help!
