Thank you!!
My problem is that, we have values between(1 to 5 mHz) lets say
(2.1, 2.3,2.5,2.9,3.3,4.2,..)that correspond to these cities/mag
stations. Each and every city has their value. I want a different
color for each city and display that color at the color with their
value. With xyouts,...,color=220, displays one color in all cities on
the map. I want different for these cities and also represent using
color bar.
please help
Thanks\
