java interface with gnuplot

[Dale]

what's are some ways to call up gnuplot into java?

one thing I would like to do is color/chromaticity related:

bring in an image
make an image map
enter two coordinates on the bitmap from textboxes
find a linear slope between the coordinates
use the slope to lookup and return the minimum and maximum perimeter
values and draw the connecting line
return the perimeter values

I think image map rules out SVG, or can I scale it to window size and
use the display bitmap of the SVG?

Googling "gnuplot Java" turns up quite a few.
gnuplot is not the right tool for that job. I'm sure there are plenty
Java libraries for image processing. You should use one of those.
