[ncl-talk] Plotting average station values on map

Hi,
I have monthly averages of ozone data and am trying to figure out how to plot them with different colors given a certain range. The only examples I can find are using dummy data, and I'm having trouble figuring out how to apply this to actual data.
My averages are:
average1 = 37.62
average2 = 39.49
average3 = 36.36
I want to display these values as different colors. For example, I want one color for values less than 37, one between 37 and 39, and one greater than 39. Here is what I've tried:
arr = (/0.,37.,39./)
do i = 0, num_distinct_markers-1
if (i.eq.0) then
indexes = ind(average3.lt.arr(37))
labels(i) = "x < " + arr(37)
end if
if (i.eq.num_distinct_markers-1) then
indexes = ind(average2.gt.arr(39))
labels(i) = "x > " + arr(39)
end if
if (i.gt.arr(37).and.i.lt.arr(39)) then
indexes = ind(average1.gt.arr(37).and.average1.lt.arr(39))
labels(i) = arr(37) + "< x < " + arr(39)
end if
end do
I'm pretty sure most of this is wrong, but I don't know what a lot of the functions mean, so any help would be appreciated!
Thanks,
Emma Nelson
