Question: I cannot get an invisible outline around a filled box when I use PlotDraw function. I thought using -1 for PenColour argument would work, but PlotDraw function did raise an invalid argument error. Is there a way of doing it at all?  

Unfortunately, PlotDraw function does not give an option to have an invisible outline around a filled box. I use the same colour for PenColour and nFill arguments to have an effect which is fairly close to what you want. The same trick may work for your case too.
