Dear list,
I would like to plot arrows with different colors according to arrow length,
and also (if
possible) with head size proportional to arrow length. The idea is to make a
quiver-like plot of
matlab with wind speed data.
So far, I´ve been able to use different colors, but I need to find a more
efficient way to recode
arrow length intervals into colors. On the contrary, I can't define different
head sizes, because
the "length" argument in the "arrows()" function seems to control the head size
of all the
arrows at once.
Hi Hector,
The color.scale function in the plotrix package may do what you want,
also have a look at the vectorField function. I think you will have to
draw the arrows one at a time or rewrite the arrows function to get
different head sizes.
