PLOTCOORD__DEFINE

Name


      PLOTCOORD

Purpose



      The purpose of this object is to create a coordinate system for generic data objects.
      It does this by saving IDL system variables. Typically, the PLOTCOORD object is updated
      *after* a plot is drawn in a window and acts to save the plotting parameters for that
      particular plot. This is useful, for example, when you wish to overplot data on the plot
      in question. You can call the draw method of the PLOTCOORD object to re-establish the plot
      parameters for overplotting.
