I'm afraid there's no way to have just the outside perimeter of the
box without having the individual boxes outlined. This has been
requested at least once before, and we already have a trouble ticket
for it (NCL-42). I've elevated the priority for this, but I can't
guarantee if it will get implemented.

One thing you might consider in order to help see that there's a white
color at the end is to set the lbLabelAlignment resource to
"ExternalEdges" (therefore getting a label at the end). Or, to get the
exact min/max of your labels on the bar, set cnLabelBarEndStyle to
"IncludeMinMaxLabels".

I'm not sure what you mean by "continuous colors for data", but in
order to get different marker colors for markers, you will need to
group them in some fashion according to what color you want them to be.

Did you see example scatter_5.ncl at:

How are you current coding the colors? It's possible you might be able
to speed up the "binning" by using the "where" and or "ind" functions.
