Class Name

---

  MGHgrGraph3D

Purpose

---

  This class implements a 3D graph with a plot volume and space for axes & annotations.
  It includes several methods for adding axes, plots, and other graphics atoms & models.

Category

---

  Object graphics.

Superclasses

---

  MGHgrGraph.

Properties

---

  The following properties (ie keywords to the Init, GetProperty & SetProperty
  methods) are supported in addition to those inherited from MGHgrGraph:
    PLOT_BOX (Init,Get,Set)
      This is a 6-element vector specifying
      the location and dimensions in normalised coordinates of the "plot volume".
      By default axes and plots are drawn around, and plots in, the plot volume.

Modification History

---

  Mark Hadfield, 2000-08:
    - Replaced existing classes MGHgrView, MGHgrGraph, MGHgrFixedGraph & MGHgrGraph3D
      with MGHgrGraph (similar to the old MGHgrView), MGHgrGraph2D (merges the old
      MGHgrGraph & MGHgrFixedGraph) and MGHgrGraph3D (similar to the old class of the
      same name but much of the logic has been moved to the superclass MGHgrGraph).
    - Removed the NewText method from this class (which therefore now inherits
      MGHgrGraph::NewText unchanged). The functionality previously provided
      by the TITLE keyword to NewText is now in a separate method called NewTitle.
      The NewTitle method requires its "text class" to have an interface very
      similar to IDLgrText, whereas the NewText method can be used with any
      graphics atom class that supports a FONT property and takes up to 1 positional
      parameter in its Init method.
  Mark Hadfield, 2004-09:
    Changed default projection of the view from 2 (perspective) to 1 (orthogonal, default)
    to work around a vector-output bug in IDL 6.1.
