      The set of contour levels.

  • Constructor Details

    • IrregularContourLevels

      public IrregularContourLevels(float[] levels)
      Constructs an instance from a list of contour values. The base contour for dashed lines shall be zero.
      Parameters:
      levels - The contour levels. They shall be ordered by increasing value.

    • IrregularContourLevels

      public IrregularContourLevels(float[] levels, float base)
      Constructs an instance from a list of contour values and a base contour level for dashed lines.
      Parameters:
      levels - The contour levels. They shall be ordered by increasing value.
      base - The base contour level. Contour lines below this value will be dashed.

    • IrregularContourLevels

      public IrregularContourLevels(float[] levels, float base, boolean dash)
      Constructs an instance from a list of contour values and a base contour level for dashed lines.
      Parameters:
      levels - The contour levels. They shall be ordered by increasing value.
      base - The base contour level. Contour lines below this value will be dashed.
      dash - dash contours below base if true

    • getLevels

      public float[] getLevels(float minimum, float maximum)
      Gets the contour levels given a data range.
      Specified by:
      getLevels in class ContourLevels
      Parameters:
      minimum - The minimum data value.
      maximum - The maximum data value.
      Returns:
      Contour levels appropriate for the given data range. No contour level will lie outside the range. The levels will be ordered by increasing value.

    • setControl

      public void setControl(ContourControl control) throws VisADException, RemoteException
      Sets a VisAD ContourControl.
      Specified by:
      setControl in class ContourLevels
      Parameters:
      control - The VisAD ContourControl to be set by this object.
      Throws:
      VisADException - VisAD failure.
      RemoteException - Java RMI failure.

    • setControl

      public void setControl(ContourControl control, float minimum, float maximum) throws VisADException, RemoteException
      Sets a VisAD ContourControl.
      Specified by:
      setControl in class ContourLevels
      Parameters:
      control - The VisAD ContourControl to be set by this object.
      minimum - The minimum value. It shall not be Float.NEGATIVE_INFINITY
      maximum - The maximum value. It shall not be Float.POSITIVE_INFINITY
      Throws:
      VisADException - VisAD failure.
      RemoteException - Java RMI failure.
