Hi Is there any free java graphing libaries out there that can be integrated into Eclipse IDE. I am looking to output results from algorithms into a xy graph of some sort or bar charts. Also is there any way to read a graph as a source of input in java

On SourceForge you'll find any number of options, including jgraph2d, jfreechart and graph2d.

By "reading a graph", do you mean graph -the mathematical concept with Euler paths, Hamiltonian circles and all that- or graphs as in two-dimensional drawings that you want to convert back to numbers?

Hi Both I am writing a tool that will display the in and outs of certain algorithms i.e Graphing algorithms, one such example would be to find a euler path so i would need to be able to read in a graph that in some way would represent visually to a person.

thanks ed.

Check out the JGraph project on SourceForge. It has a JGraphPad add-on which allows you to lay out graphs manually. I would imagine that it can show predefined graphs as well.
