#59 plot Pareto Optimal solutions from NSGA II and other heuristics

[Anonymous]

I would like to plot the Pareto Optimal solutions from NSGA-II according to my problem design.
I would like also to plot some other solution points as well that I got from other heuristics not using MOEA Framework.
Something like:
-10 Pareto front solutions got from NSGAII using MOEA Framework. Each solution has two objectif values (objectif 1, objectif 2)
-4 other solutions got from other algorithms. Each solution has two objectif values (objectif 1, objectif 2)

Thnaks in advance

For plotting you will need to use a different program/software. If you want plots in Java, JFreeChart is a good option. I also frequently use R since it is freely available. For example, below plots three points with color with R:

x = matrix(c(s1.obj1, s1.obj2, s2.obj1, s2.obj2, s3.obj1, s3.obj2),
             ncol=2, byrow=T)
col = c("red", "red", "blue")
plot(x, col=col)

using MOEA Framework and Java is there any existing API or tool already there to do this job? I don't want to do it from scratch in java
