Hi Muhammad,<br>
<br>
the lines are resulting from the gsn_polyline_ndc call, where all
given line points were connected. What you want are three single
boxes, so you have to define three boxes like below.<br>
<br>
xbox1 = (/
lon2(0,0),lon2(0,nx2),lon2(ny2,nx2),lon2(ny2,0),lon2(0,0) /)<br>
xbox2 = (/
lon3(0,0),lon3(0,nx3),lon3(ny3,nx3),lon3(ny3,0),lon3(0,0) /)<br>
xbox2 = (/
lon4(0,0),lon4(0,nx4),lon4(ny4,nx4),lon4(ny4,0),lon4(0,0) /)<br>
<br>
ybox1 = (/
lat2(0,0),lat2(0,nx2),lat2(ny2,nx2),lat2(ny2,0),lat2(0,0) /)<br>
ybox2 = (/
lat3(0,0),lat3(0,nx3),lat3(ny3,nx3),lat3(ny3,0),lat3(0,0) /)<br>
ybox3 = (/
lat4(0,0),lat4(0,nx4),lat4(ny4,nx4),lat4(ny4,0),lat4(0,0) /)<br>
<br>
datatondc(map, xbox1, ybox1, xbox_out1, ybox_out1)<br>
datatondc(map, xbox2, ybox2, xbox_out2, ybox_out2)<br>
datatondc(map, xbox3, ybox3, xbox_out3, ybox_out3)<br>
<br>
gsn_polyline_ndc(wks, xbox_out1, ybox_out1, lnres)<br>
gsn_polyline_ndc(wks, xbox_out2, ybox_out2, lnres)<br>
gsn_polyline_ndc(wks, xbox_out3, ybox_out3, lnres)<br>
<br>
Bye,<br>
