Hi Aaron,

If you set the fill-color of the Canvas before drawing anything
on it, the child frame drawn later will inherit the fill color of
the parent (canvas). So one alternative is:
   canvas->SetFillColor(0); h->Draw();

If this is not convenient, what you are looking for is;
   canvas->GetFrame()->SetFillColor(0);
