A while ago I blogged about the Function Grapher Online, a free graphing calculator available on the internet. It is a great tool that is very simple, but might appear a bit clunky and ugly at times. I believe that it was created by someone in the spare time because a better alternative didn’t exist or just as a proof of concept. However, in the last couple of days I stumbed across a more professional looking (but still free) online graphing calculator, called FooPlot. Not only does it sport a cleaner interface, but it also has features that Function Grapher Online did not have.

Features

• panning the graphs is much easier with the drag and move interface
• support for different function types
  • simple functions
  • polar
  • parametric
• finding of roots
• finding of intersections
• 3D graphs
• export plots in different formats (SVG, EPS, PNG, PDF)
• sharing of your plots through URL’s

There are a few features that I am missing though, and hopefully will be implemented sometimes in the near future. For example, it would be great if I could enter more than 5 functions. Also tools for finding maximums and minimums would be much appreciated, and probably not that hard to implement too.
