Hi all
In this program I want to show vector arrows on the map. I got cities
and colorbar, Next to cities I want to plot an Arrow vector of
amplitudes for the given time and plot another arrow vector for phase
angle and show the rotation of phase. I tried but I am not winning.
If I can manage to solve this, I will display those values with colors
on the colorbar. Any help will be highly accepted.
The program is like this
loadct,33

I will be happy if you can help me to achieve this
many thanks
