profile: make DiveCartesian axis grayscale aware

Browse source 
I doubt that this is necessary, but since most of the rest
of the profile code passes "isGrayscale" to "getColor()",
do the same here for consistency.

To avoid storing the isGrayscale flag, just create the pens
at construction time and store those.
