Dear all,

I want to plot a track via Gviz in mountain type. However, it looks like that fill.mountain does not work. How do I fill the area under the curve in black? Thanks.

+  end = "end", data = "score", type = "mountain", window = -1,
+  windowSize = 1500, fill.mountain = "black",
+  col.mountain = "black", name = "GC Percent")
