Absolutely! But because it's saturday, I'm not going to look it up in
the javadoc for you ;-)
Instead, have a look at the tutorial, section 4.2
http://www.ssec.wisc.edu/~billh/tutorial/s4/Section4.html#section4_2
where the ContourWidget is introduced. After you've created and added an
iso-contour map to your display, create the widget with
contourWid = new ContourWidget( isoMap );
and add it to your JFrame or to your favourite GUI component. On the
widget you should first click on the dashed-lines-below-base checkbox,
then set the base value to zero (you said dashed values are negative)
and that's about it.
Of course there's a way to do the same by calling the appropriate
methods, but I'm not acquainted with them. Anyway, I recommend using the
widget.
Cheers,
Ugo
