plotting pareto frontier for more than 2 objectives

[Betty]

Hi All,

My apologies  - this question is not directly related to the DEAP, but, I thought you might give me some help.

I used NSGA-II to solve a multi-objective problem (maximise, minimise and minimise).

I tried to plot my results using a 3D scatter diagram. Blue points are the individuals evolved throughout the algorithm, and red points are the final hof values (pareto frontier).

Is there a better way to plot this?

Many thanks for your help.

Pair plots are a good way to plot multidimensional data.

Thanks François,

Let me check I understood you correctly, so instead of plotting 3 of the objectives using a 3D plot, just plot them in pairs?

Exactly

Great, thanks!
