Anyone have a good algorithm (or aware of reasonable conceptual
heuristic) for displaying continuous data as a "gradient?"
I have a set of data points along a continuum which cluster modally.
Displaying the modes as hot spots on a continuum has been proposed as a
display that would resonate with our users (like blue to red for rare to
Pointers to Tufte-esque senstive discussions of the algorithms that
would support such a display would be appreciated.
