RooPlot: both line and fill of a pdf component

Dear Experts,
I would like to plot a curve with a line and a fill pattern in RooFit,
for example:

TotalPDF->plotOn(myFrameX, Components(*MassSignal), LineStyle(7), LineColor(kBlue), FillStyle(3345), FillColor(kBlue), DrawOption(“LF”));

If I do that, the plot shows only the fill, without the line.
Can you please tell me how can I plot both line and fill ?

Many thanks,

  • Mauro.
