Class Description

 Create an empty frame with the specified x-axis limits.

 Create an empty frame with the specified x- and y-axis limits.

 Create an empty frame with the specified x- and y-axis limits
 and with labels determined by the specified variables.

 Create an empty frame with the specified x- and y-axis limits
 and with labels determined by the specified variables.

 Create an empty frame with its title and x-axis range and label taken
 from the specified real variable. We keep a clone of the variable
 so that we do not depend on its lifetime and are decoupled from
 any later changes to its state.

 Create an empty frame with its title and x-axis range and label taken
 from the specified real variable. We keep a clone of the variable
 so that we do not depend on its lifetime and are decoupled from
 any later changes to its state.

 Perform initialization that is common to all constructors.

 Delete the items in our container and our iterator.

 A plot object is a frame without any bin contents of its own so this
 method always returns zero.

 A plot object is a frame without any bin contents of its own so this
 method always returns zero.

 A plot object is a frame without any bin contents of its own so this
 method always returns zero.

 Add a generic object to this plot. The specified options will be
 used to Draw() this object later. The caller transfers ownership
 of the object with this call, and the object will be deleted
 when its containing plot object is destroyed.

 Add a TH1 histogram object to this plot. The specified options
 will be used to Draw() this object later. "SAME" will be added to
 the options if they are not already present. Note that histograms
 should probably not be drawn with error bars since they will not
 be calculated correctly for bins with low statistics, and will
 not be accounted for in the automatic y-axis range adjustment. To
 histogram data in a RooDataSet without these problems, use
 RooDataSet::plotOn(). The caller transfers ownership of the
 object with this call, and the object will be deleted when its
 containing plot object is destroyed.

 Add the specified plotable object to our plot. Increase our y-axis
 limits to fit this object if necessary. The default lower-limit
 is zero unless we are plotting an object that takes on negative values.
 This call transfers ownership of the plotable object to this class.
 The plotable object will be deleted when this plot object is deleted.

 Update our plot normalization over our plot variable's fit range,
 which will be determined by the first suitable object added to our plot.

 Update our plot normalization over our plot variable's fit range,
 which will be determined by the first suitable object added to our plot.

 Update our y-axis limits to accomodate an object whose spread
 in y is (ymin,ymax). Use the specified y-axis label if we don't
 have one assigned already.

 Draw this plot and all of the elements it contains. The specified options
 only apply to the drawing of our frame. The options specified in our add...()
 methods will be used to draw each object we contain.

 Print info about this plot object to the specified stream.

  Standard: plot variable and number of contained objects
     Shape: list of our contained objects

 Return the name of the object at slot 'idx' in this RooPlot.
 If the given index is out of range, return a null pointer

 Return the name of the object at slot 'idx' in this RooPlot.
 If the given index is out of range, return a null pointer

 Return a pointer to the line attributes of the named object in this plot,
 or zero if the named object does not exist or does not have line attributes.

 Return a pointer to the fill attributes of the named object in this plot,
 or zero if the named object does not exist or does not have fill attributes.

 Return a pointer to the marker attributes of the named object in this plot,
 or zero if the named object does not exist or does not have marker attributes.

 Return a pointer to the text attributes of the named object in this plot,
 or zero if the named object does not exist or does not have text attributes.

 Return a RooCurve pointer of the named object in this plot,
 or zero if the named object does not exist or is not a RooCurve

 Return a RooCurve pointer of the named object in this plot,
 or zero if the named object does not exist or is not a RooCurve

 Change the order in which our contained objects are drawn so that
 the target object is drawn just before the specified object.
 Returns kFALSE if either object does not exist.

 Change the order in which our contained objects are drawn so that
 the target object is drawn just after the specified object.
 Returns kFALSE if either object does not exist.

 Find the named object in our list of items and return a pointer
 to it. Return zero and print a warning message if the named
 object cannot be found. If no name is supplied the last object
 added is returned.

 Note that the returned pointer is to a
 TObject and so will generally need casting. Use the getAtt...()
 methods to change the drawing style attributes of a contained
 object directly.

 Return the Draw() options registered for the named object. Return
 an empty string if the named object cannot be found.

 Register the specified drawing options for the named object.
 Return kFALSE if the named object cannot be found.
