What is the difference between a 2D graph and
a 'dynamic 2D graph'?  The only thing I can think
that would explain the 'dynamic' is if the data is
continually changing, and so is the graph.

(An 'oscilloscope trace' as might be seen in WinAmp or
other music players, is an example of plotting data that
continually changes.)

I do not understand what you mean by that, especially
in regards to 'dumping y values'.

JFreeChart is commonly recommended for drawing
charts and graphs.  <http://www.jfree.org/jfreechart/>
Since I do not entirely understand your requirement, I
cannot be sure if it 'fits the spec.'.

JFreeChart is free.  Though with the vast amount of free
software libraries/APIs available to Java programmers*,
they generally do not recommend or offer links to
'cracked' commercial software - if that is what you
were asking.

* Or perhaps because they are so ethical ..OK - maybe not.

Hi!
As Andrew said: JFreeChart.
Have a look at the Demo, you can start via Java Web Start. There
actually is a diagram in the demo which supports that. The only thing
there is to say, it is not a normal linechart, but a TimeSeriesChart, so
the x-axis is the time line...
So if you want the x-axis to be the timeline, it might be perfect for you.
If you have a (deeper) look at it, you might find a way to use these
dynamics with XYCharts/LineCharts, too.
