If anyone has any other suggestions for their favourite (preferably free!) software for this kind of thing, whether online or offline, please let me know in the comments! Happy plotting! Well, there’s this one, which (bizarrely) seems to be aimed at kids, and this one which seems OK-ish (but requires sign-up, so y’know… fail) but they’re nothing I’d heartily recommend. I’ve also had a good poke-around online and haven’t found any decent online tools for making nice-looking basic plots.

People have told me that R can produce some very nice plots, and I’m sure they’re right, but because of the command-line interface it’s something that I’d hesitate to recommend for beginners/students. I normally like to recommend free software on this site, but unfortunately I’ve never found anything which compares to these two recommendations in the freeware/shareware world. The unfortunate downside of both SigmaPlot and Graphpad Prism is that they are both commercial pieces of software which cost real money (although Prism does have a 30-day trial period in which you can try it out). A sample Prism plot – simple, clear, clean… nice.
