Drawing a graph

Hi all!

I want to draw a directed, possibly cyclic graph in some GUI. What would
probably be the best approach to that? What classes and what methods in
the JDK do I have to look for? I probably have to override some paint
method, but I'm not sure what to subclass etc. I have never done
something like this before.

Any suggestions?

Karsten

Try a 3rd-party graphing library. I have used Touchgraph with much
success, but there are others.

Common way is subclassing JPanel of JLabel and override its
paintComponent() method. The argument Graphics object can be easily
casted to Graphics2D object so you can utilize some sophisticated
drawing methods.

Do you want to code it yourself, or do you
just want the functionality Karsten?

I believe there are quite a number of free,

(many, many..) ]

..and possibly open source,

(44,000) ]
graphing packages already exist.
