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:

RooPlot *p = y.plotOn(x.frame());
p->getAttMarker("curve_y")->SetMarkerStyle(20);
p->setDrawOptions("curve_y","PL");
p->Draw();

To retrieve a RooCurve from a RooPlot, use RooPlot::getCurve().
