Your earlier question had a full world map. That was the context for Jim's
reply, which did plot a two headed arrow above the legend in your earlier
question. Now you have restricted the plot region to Europe so the coordinates
of -100,-140,100,-140 no longer are on the visible plot area. You need to
decide where you want the arrows using sensible coordinates.
