Plotting Pareto fronts in 3D

Various examples using mooplot.plot_pf().

import moocore
import mooplot

Points

data = moocore.get_dataset("spherical-250-10-3d.txt")
# Select only the last 3 datasets
data = data[data[:, -1] >= 8, :]
fig = mooplot.plot_pf(data, title="Spherical")
fig

Three objective surface

Use the type=”surface” argument to draw a smooth 3D surface for each dataset.

fig = mooplot.plot_pf(data, type="surface")
fig

Three objective surface+points

Use type=”surface, points” to add both points and surfaces to the plot. You can compare the surface of one dataset to the points of another by clicking on “set 1” and “set 2 points” in the legend to hide some of the points and surfaces.

data = moocore.get_dataset("uniform-250-10-3d.txt")
data = data[data[:, -1] >= 8, :]
fig = mooplot.plot_pf(data, type="surface, points", title="Uniform")
fig

Three objective cube graph

Use type=”cube” to add a cuboid for each point.

Warning

This may be slow in large datasets.

fig = mooplot.plot_pf(data, type="cube")
fig
