Re: Marker colors in scatter plot

The xyMarkerColors resource only works if you have multiple curves.
It's not a way to take points in a single curve and color them
differently.

If you want the first three red and the second three blue, then
create two curves:

x = ispan(1,6,1)
y = new((/2,dimsizes(x)/),float)

y(0,0:2) = x(0:2)+3 ; The rest of y will be missing values
y(1,0:2) = x(3:5)+3

Now set:

res@xyMarkerColors = (/"red","blue"/)

The red will apply to the curve represented by y(0,:), and
blue will apply to y(1,:).
