Map_set & Plots [message #2446]

I am trying to use map_set to plot the ground-track of a spacecraft and use
plots to draw a line from the ground track in the line-of-sight (los)
direction. I can plot the points fine, but cannot seem to get them all to connect. Here is my attempt:
map_set,/mercator,/grid,/continent
oplot,long_los,dec_los,psym=6,color=100
oplot,long_sat,dec_sat,psym=5,color=185
for i=0,302 do plots,[long_sat(i),long_los(i)],[dec_sat(i),dec_los(i)]

This only works on about half of the points. Only the points that are East of
Greenwich are plotted, and nothing west. Anyone have any suggestions?
