Gwyn,
After experimenting directly with the PS output, I have to second
Kenneth's remarks. The PS output from your example contains no
operators that set line colors to anything other than black. The axes
look gray in ghostview, though our crummy old HP Laserjet prints them
as black. The data curve, however, appears black in ghostview.
Inspection of the PS output shows that the data curve is twice as
thick (20 setlinewidth) as the axes (10 setlinewidth).
Try the XTHICK and YTHICK keywords in PLOT. [xy]thick=2.0 should look
black.
