This is called a radial gradient fill in SVG speak.

Hi Alex,
This is harder than it looks for a number of reasons. First you want
to desaturate the colors as you move out, which requires something
more sophisticated than the approximation I have done in the code
below. RGB may not be the best colorspace to use for this. Second is
that when you draw
There are lots of different ways to do this. I don't use plotrix, which
uses base R graphics functionality, so I can't help you with your current
approach. However, it is easy to do this "by hand" in the newer,
object-based grid package (on which ggpot and lattice are built) . The
idea, which proba
Hi all,I would like to draw a simple circle where the color gradient follows
the rule color = 1/(r^2) where r is the distance from the circle. I would also
like to add a color bar with values going from -40 to -110 (and associate those
with the color gradient that fills the circle).
So far I exp
