I'm looking for something that will allow me to graph 50K+ data points on a Cartesian plane, preferably with lots of setting and options for colors, etc.
Note that at this load, LibreOffice crashes.
This doesn't have to work on both Linux and Windows but comparability is a bonus for sure.
As it turns out, Microsoft Excel handles 50,000 points quite well, but I haven't found a good way to handle the data on Linux...
