One-dimensional graphical representation of a real-valued function.
A curve is approximated by straight line segments with end points chosen to give a "good" approximation to the true curve. The goodness of the approximation is controlled by a precision and a resolution parameter.
A RooCurve derives from TGraph, so it can either be drawn as a line (default) or as points:
To retrieve a RooCurve from a RooPlot, use RooPlot::getCurve().
