drawing curve for given co-ordinates

fs11 · 06-02-2011, 01:11 PM

Hello all,

I am looking to draw a curve for a given set of coordinates using java. For example;

(1,2)
(2,4)
(3,6)

I am aware that a straight line graph can be drawn for a given coordinates using Jfree, but I am not sure about drawing the curve. Any hints on what might be a good java class to use, Any help would be appreciable.

Thanks in advance.

Splines ? Or, for just three points, quadratic (second order polynomial) approximation ?

Any thing that would allow the 'curve' to pass through the given co-ordinates.

Look up on the net

polynomial approximation
Lagrange polynomials
.
