    //  Root > hpxpy.Draw();
    //  Root > c1.AddExec("exsel","select_hist()");

    //  projection along X of the bin corresponding to the Y position
    //  of the mouse. The resulting histogram is fitted with a gaussian.
    //  A "dynamic" line shows the current bin position in Y.
    //  This more elaborated example can be used as a starting point
    //  to develop more powerful interactive applications exploiting CINT
    //  as a development engine.
