I am moving this discussion to Java in General(intermediate).

Dinesh,
Yes, of course it is possible to draw a graph in Java... I can't really provide you with code because the question is too general... It depends on how you want to do it... Do you want to draw a bar graph, a pie chart, a line graph, etc.? You can also create a custom component that will display a graph, or just have the graph hard coded into your application. Personally, I would make a component that could be added to any application ( more OO, and easier to reuse! ) and use some type of collection inside to save all the graphs, their values and associated colors inside the component. I would then have the paint() method of the component go through all the graph values and paint them however you wanted. (points, lines between points, filled rectangles, arcs, etc. , depending on the type of graph you want...)
HTH,
-Nate

Hopefully someone still looks here I see the last entry was the 16th. I need help creating a graph with a Java program/applet. Right now, I am looking at the need for a dynamic line graph, based on data that is acquired from a file. Examples would be fantastic, but a resource where I could possibly find this info would also be helpful. (ASAP)
Thanks

This link may be of interest for you. JFreeChart is a free graphing tool. Not sure how good it is, but have a look.

You can try RChart
it includes a Visual Tool for building the charts. Then you canuse the charts very easily as servlet, applet or bean.
