BasicTooltipProvider, HasPhase2D.Data2Phase
Enclosing class:
ParaGraph
public class ParaGraph.TraitMap extends Object implements HasPhase2D.Data2Phase, BasicTooltipProvider

    • TraitMap

      public TraitMap()
      Create new trait map.

  • Method Details

    • reset

      public void reset()
      Description copied from interface: HasPhase2D.Data2Phase
      Reset the map. For maps that implement automatic scaling of the axes this should reset the range of the phase plane.
      Specified by:
      reset in interface HasPhase2D.Data2Phase

    • setTraits

      public void setTraits(int[] x, int[] y)
      Description copied from interface: HasPhase2D.Data2Phase
      Allows custom implementations to set the traits displayed on phase plane axis.

      In multi-species models the traits are numbered sequentially, i.e. if the first species has nTraits then e.g. an index of nTraits+1 refers to the second trait of the second species. Be careful to account for vacant types in density based models.

      Specified by:
      setTraits in interface HasPhase2D.Data2Phase
      Parameters:
      x - the array of indices of horizontal trait(s)
      y - the array of indices of vertical trait(s)

      getTraitsX in interface HasPhase2D.Data2Phase
      Returns:
      the array of indices

    • getTraitsY

      public int[] getTraitsY()
      Description copied from interface: HasPhase2D.Data2Phase
      Get the array of indices of traits displayed on the vertical axis of the phase plane.
      Specified by:
