Plotting pareto frontier for 3 objectives

[tanguyen77]

Hi, is it possible to plot the pareto frontier based on the model posterior for three objectives using "compute_posterior_pareto_frontier"?

Hello there! Unfortunately not. The current implementation of
compute_posterior_pareto_frontier is explicitly written for two objective metrics.

@tanguyen77 how would you envision this to work? Should this produce a 3D plot (I assume this will often be very hard to read / understand without making it interactive (so you can rotate etc.)? Another thing that one could do would be to plot a number of different frontiers for two objectives, each conditioning on a different level of the third.
