Hi guys,

I need to generate a contour or 'heat' map using Java. Can anyone point me to the correct directions please? e.g what libraries would i require, would i need swing knowledge or are there 3rd party software that i can use? thanks alot in advance!

Hi,

Welcome to JavaRanch!

First, a bit of business: you may not have read our naming policy on the way in. It requires that you use a full, real (sounding) first and last name for your display name. Obviously fake names aren't OK. You can change your display name here. Thanks!

As to your question: there are many chart-drawing packages for Java, both free ones like JFreeChart and commercial ones. Maybe someone else has some specific suggestions.

Contour mapping involves two problems:
1. extrapolating between known datapoints to locate values where contours should be drawn while respecting the logic of the underlying data
2. drawing smooth curves between locations found in 1 - also respecting the logic of the underlying data.

This example shows use of 2d graphic to draw smooth curves between datapoints.
This is really a huge area, so you better refine your requirements early, coping with the graphics side is the least of your problems.
