Pareto Scatter 2D

The Pareto Scatter 2D chart displays trial values for two objective functions as a scatter plot, visualizing the Pareto front.

Controls

Item Description
X / Y axis Use the X and Y dropdowns to select which objective is plotted on each axis.
Infeasible trials (constrained studies only) These are always shown in a distinct color when the study has constraints; there is no control to hide them.

Operations

Pan, zoom, reset, point hover/click, and Shift-drag region select follow the standard 2D chart controls.

Item Description
Hover The point tooltip shows the trial number and objective values.
Trial detail Click a point to open its detail modal.

How to Read

  • Pareto front points (red): non-dominated trials. No other trial is better in both objectives simultaneously, so these are your best candidates.
  • Non-Pareto points (blue): dominated trials. Another trial is at least as good in every objective and strictly better in at least one.
  • Infeasible points: trials that violate constraints, shown in a distinct color.
  • Unselected points (greyed): points outside the current selection region.
  • Brushing/linking: selections made in other widgets are received and highlighted here.
