    SafeDisposable
    public class PoGeneralizedBar
extends PoBar
    Class to build generalized bars. Build bars on 1D mesh (PoIrregularMesh1D or PoRegularMesh1D), where each bar is defined by a sub-scene graph. The field bars is used to define the sub-scene graph of each bar. If the number of sub-scene graphs is inferior to the number of bars to draw, they are cyclically used. The field scaleFactor specifies a possibly non uniform scale applied to each bar. The orientation of the bars can be horizontal or vertical. The abscissas (ordinates if HORIZONTAL orientation) of the bars are given by the geometry of the current mesh 1D, and the height (width if HORIZONTAL orientation) are given by one of the value-set of the current mesh 1D specified by the field yValuesIndex. A threshold defines the origin of the bars. This value is either an ordinate (VERTICAL orientation) or an abscissas (HORIZONTAL orientation). This class also takes into account of the current mesh 1D hints (PoMesh1DHints) and the current mesh 1D filter (PoMesh1DFilter) to filter the geometry of the current mesh 1D .

    The interpretation of colorBinding is the following :

    • INHERITED: All bars are colored with the same inherited color.
    • PER_PART or PER_VERTEX : A color is used for each bar.

    File format/default:

    PoGeneralizedBar {

      colorBinding INHERITED
      yValuesIndex 0
      colorValuesIndex 1
      material NULL
      bars NULL
      scaleFactor 1 1 1
      orientation VERTICAL
      threshold 0.0
    }

    • Field Detail

      • bars

        public final SoMFNode bars
        Defines the sub-scene graphs used for each bar. If the number of sub-scene graphs is inferior to the number of bars to draw, they are cyclically used. Each sub-scene graph defining each bar is considered to be specified vertically in the plane XY.

      • scaleFactor

        public final SoSFVec3f scaleFactor
        Specifies a possibly non uniform scale applied to each bar. If the orientation is VERTICAL, only the X and Z components are used, and if the orientation is HORIZONTAL, only the Y and Z components are used. If a component has a negative value, the scale in the component direction is relative to the height (resp. width) of the histogram, otherwise this an absolute scale.
