Hi,

I am using the following track definition line to display copy number data
in two-color BedGraph:

track type="bedGraph" name="Track1" description="Track 1" visibility=full
color=255,0,0 altColor=0,255,0 autoScale=off viewLimits=-2:2

All is fine except the track label shows up as red due to the color
parameter setting. The effect I would like to achieve is having red bars for
positive data and green bars for negative data, while the track label
remains black.

Is there a way to set the color of the track label separately from the
colors of the bars? I tried setting itemRgb but it didn't appear to work on
BedGraph.

Thanks,
Tien-chi
