Class PoValuedMarkerField

  • All Implemented Interfaces:
    SafeDisposable
    public class PoValuedMarkerField
extends PoGraphMaster
    Class for a valued markers field. Class to build a valued markers field in the plane XY. A valued markers field is a list of markers which can be colored and can have different sizes. By default all markers have the same size and the same color.

    Colors of the markers depend on the current data mapping. If the method setDataMapping(dataMapping) is called, the current data mapping is "dataMapping". Otherwise the current data mapping is specified in the current inherited state (cf property node PoDataMapping and its derived classes). If there is no current data-mapping (i.e setDataMapping() not called and no PoDataMapping node traversed before in the scene graph), all markers get the same color which is the inherited color.

    File format/default:

    PoValuedMarkerField {

      point 0 0
      value 0
      size 0
      markerString "."
    }

    • Field Detail

      • point

        public final SoMFVec2f point
        List of coordinates for the markers.

      • value

        public final SoMFFloat value
        List of values used to color the markers. If the number of values is equal to number of points of point , marker have a color depending on the current data mapping (see description of PoValuedMarkerField), otherwise all the markers have the same color.

      • size

        public final SoMFFloat size
        List of sizes used to calculate the marker sizes. If the number of sizes is equal to number of points of point , marker have a size depending on size, otherwise all the markers have the same size.

      • markerString

        public final SoSFString markerString
        The markers are defined by a string. If this field is equal to ".", the markers are SoPointSet shapes, otherwise SoText2 shapes. To change the font of text markers, set the catalog part appearance.font.name . Be careful, for the moment, text markers are not vertically aligned.

    • Constructor Detail

      • PoValuedMarkerField

        public PoValuedMarkerField()
        Default constructor.

      • PoValuedMarkerField

        public PoValuedMarkerField​(SbVec2f[] _point,
                           float[] _value,
                           float[] _size)
        Constructor.

    • Method Detail

      • getDataMapping

        public PbDataMapping getDataMapping()
        Gets a reference to a PbDataMapping object, used to the association value- color.

      • setDataMapping

        public void setDataMapping​(PbDataMapping dataMapping)
        Sets a reference to a PbDataMapping object, used to the association value- color. If this method is not called (or called passing NULL as argument), this is the data mapping defined in the current inherited state (defined with the property node PoDataMapping and its derived classes) which is used.
