A RooPlot is a plot frame and a container for graphics objects within that frame.
As a frame, it provides the TH1-style public interface for setting plot ranges, configuring axes, etc. As a container, it holds an arbitrary set of objects that might be histograms of data, curves representing a fit model, or text labels. Use the Draw() method to draw a frame and the objects it contains. Use the various add...() methods to add objects to be drawn. In general, the add...() methods create a private copy of the object you pass them and return a pointer to this copy. The caller owns the input object and this class owns the returned object. All RooAbsReal and RooAbsData derived classes implement plotOn() functions that facilitate to plot themselves on a given RooPlot, e.g.
These high level functions also take care of any projections or other mappings that need to be made to plot a multi-dimensional object onto a one-dimensional plot.

When a file has been opened before a RooPlot instance is created, this instance will be associated to the file. Closing the file will e.g. write the instance to the file, and then delete it. Like TH1::AddDirectoryStatus().

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 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.

Add a TH1 histogram object to this plot.

void RooPlot::createInternalPlotVarClone | ( | ) |
Replaces the pointer to the plot variable with a pointer to a clone of the plot variable that is owned by this RooPlot.
The RooPlot references the plotted variable by non-owning pointer by default since ROOT 6.28, which resulted in a big speedup when plotting complicated pdfs that are expensive to clone. However, going back to an owned clone is useful in rare cases. For example in the RooUnitTest, where the registered plots need to live longer than the scope of the unit test.

normalize | If true, the residuals are divided by the error of the histogram, effectively returning a pull histogram. |
