ViewPort background color

[Rosmkr]

When I set the background color for ViewPort graph.getViewPort().setBackgroundColor(Color.Black)
It fill a legend color too.How fill background color only to ViewPort, square where pain the GraphLine?
I use GraphView-4.2.1.jar library.There is no issue in library GraphView-4.0.1.jar.
