Use a buffered image if you need double buffering, but even if you are,
it is more efficient to make the BI the same size as the applet and
scale the points to fit the BI as they are being drawn.
The point is to increase the apparent resolution. It's a trick that's common used in video games: http://en.wikipedia.org/wiki/FSAA
However, if this is a line plot, I imagine it'd be more efficient to scale the data itself, as Andrew mentioned in another branch of this thread, and simply enable anti-aliasing when drawing your lines.
