MGHGRCOLORBAR2__DEFINE

Class Name


  MGHgrColorBar2

Purpose


  This class implements a colour bar, ie a rectangular bar
  showing a mapping between numeric values and colours.

Category


  Object graphics.

Superclasses


  This class inherits from IDLgrModel.

Properties


  The following properties are supported:
      AXIS (Get)
          This keyword returns a reference to the axis object. It can be used
          to modify the axis properties.
      BYTE_RANGE (Init,Get,Set)
          The range of byte values to which the data range is to be mapped.
      COLORSCALE (Init)
          A reference to an object from which default colour mapping information
          (BYTE_RANGE, DATA_RANGE and PALETTE) can be retrieved.
      DATA_RANGE (Init,Get,Set)
          The range of data values to be mapped onto the indexed color range.
          Data values outside the range are mapped to the nearest end of the range.
      DELTAZ (Init,Get,Set)
          Vertical spacing in normalised units between the components of the
          object, needed to control visibility. If this property is
          not set, then the spacing is set at draw time, based on the view's
          ZCLIP property--the value is 2*(ZCLIP[0] - ZCLIP[1])/65536, which
          for the default ZCLIP is 6.1E-5. DELTAZ should only need to be
          set explicitly if the object or its parent is transformed before
          drawing.
      LOCATION (Init,Get,Set)
          Location of the lower left corner of the rectangle in data units.
      DIMENSIONS (Init,Get,Set)
          Horizontal & vertical dimensions of the rectangle in data units.
      PALETTE (Init,Get,Set)
          A reference to the palette defining the byte-color mapping.
      TICKIN (Init,Get,Set)
          Controls whether tick marks are directed inwards (1) or outwards (0).
          The default is 0.
      TITLE (Init,Get,Set)
          A reference to a text object representing the axis title. If this is
          specified as a string, then a text object is created automatically
          using the current setting of the FONT property.
      XCOORD_CONV (Init,Get,Set)
      YCOORD_CONV (Init,Get,Set)
      ZCOORD_CONV (Init,Get,Set)
          Coordinate transformations specifying the relationship between
          normalised & data units.
      XRANGE (Get)
      YRANGE (Get)
      ZRANGE (Get)
          Position of the extremes of the object in data units. ZRANGE is
          not finalised until the object is drawn.
