How to make a graph in Java using Netbeans?

How can I create a graph in Java using Netbeans? Most of the forum posting that I find on the internet that answer this question just lead to a link to JFreeChart which I wouldn't mind trying but I am on a tight deadline 24hrs and I would like some good advice on the easiest method to do this (I don't want to go 8 hours in the wrong direction).  I don't mind if it isn't elegant I just need it to be able to graph two arrays within a project.

This is waht  this thing plots: 

But you know - very important to have exactly specific versions of jars - so
I could do it only with jfrechart-0.9.20 and most importnat jcommon-0.9.5.jar

Neither jcommon-1.., nor jcommon-0.9.1 would work.
Look, maybe it qwould work for you

JFreeChart is also simple, and there are many exmaples avialble:

Thank you again for the suggestions.  I am trying to create 3 plots and I have done so with Matlab so that I can check my results.  

@object - Is there an example using Swing that would work for a line graph?

@yan - I looked at the JFreeChart and it has a line graph would it generate this type of output?

not aware of any simple line graph examples sorry.
shouldn't be too hard to adapt the code above.
With a line graph your just draw a line from each data point to the next so its actually simpler than a line graph.

I think that could work for me but I am finding installing the JFreeChart very difficult.

I will try your suggestion and start a new question on installing JFreeChart.  

Thanks.  That will do the trick.

JFreeChart is an excellent software.  Installing it can be a bit tricky but once you have it in the graph quality is excellent.
