.SH CLASSES
  The Plotter widget is a subclass of Constraint.  The class pointer
  is atPlotterWidgetClass, and the class name is AtPlotter.
  
+ .SH PRIVATE CHILD OBJECTS
+ There are six private children of the Plotter widget:
+ .BR xaxis ", " yaxis ", " y2axis ", "
+ .BR xframeaxis ", " yframeaxis ", and " y2frameaxis .
+ They are all created at widget creation time and are AtAxis objects.
+ (Programs can get the object pointer using the
+ .BI AtPlotterGet object ()
+ routines.)  Resources for each of these axes can be set in the usual
+ way.  There are three main axis objects and three frame axis objects.
+ The X axis is along the bottom of the graph, and all plots use the
+ same X scale.  There are two Y axes that are completely equivalent,
+ called the Y and Y2 axes.  The Y axis is on the left of the main graph
+ area, the Y2 axis is on the right.  A given graph may use either or
+ both Y axes.  (The
+ .B useY2Axis
+ constraint variable for each plot determines which Y axis it is
+ associated with.)
+ 
+ In addition to being used for scaling, each of the three main axes can
+ be independently displayed or not displayed by setting the 
+ .B displayed
+ constraint resource for the axis object.  (Previous versions insisted
+ on displaying the X and Y axes, and had an AtPlotter resource to
+ control the display of the Y2 axis.)  The results of setting the
+ .B displayed
+ resource to 
+ .B false
+ for both 
+ .B yaxis 
+ and
+ .B y2axis
+ is undefined.
+ 
+ The three frame axes are used when the 
+ .B framedAxis
+ resource is set to
+ .BR True .
+ In this case, the xframeaxis is always drawn, the yframe axis is drawn if
+ the y2 axis is not being displayed, and the y2frameaxis is drawn if the
+ yaxis is not being displayed.  The 
+ .B displayed
+ constraint resource is ignored for frame axes.
+ The 
+ .B autoNumber
+ resource of frame axes is forced to
+ .BR False ,
+ and the numbering of frame axes is forces to be the same as for the
+ corresponding main axis by the AtPlotter widget code.
