<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I plot wind barbs using the maskout function. Each
color corresponds to a different wind intensity (barbs), for
example:</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV>'set ccolor 9'</DIV>
<DIV>'d maskout(u*2,mag(u,v)-0;maskout(v*2,1.25-mag(u,v))'</DIV>
<DIV>
<DIV>'set ccolor 14'</DIV>
<DIV>'d maskout(u*2,mag(u,v)-1.26;maskout(v*2,3.75-mag(u,v))'</DIV>
<DIV>
<DIV>'set ccolor 4'</DIV>
<DIV>'d maskout(u*2,mag(u,v)-3.76;maskout(v*2,6.25-mag(u,v))'</DIV>
<DIV>e.t.c.</DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I would like to skip barbs in both x and y
direction</FONT></DIV>
<DIV><FONT size=2 face=Arial> </FONT></DIV>
<DIV><FONT size=2 face=Arial>I tried to use the skip function,
</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV>'d skip(maskout(u*2,mag(u,v)-3.76;maskout(v*2,6.25-mag(u,v)),2,2)</DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>but it didn't work!</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Would somebody please help me? </FONT></DIV>
<DIV><FONT size=2 face=Arial>Any idea?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Thanks in advance</FONT></DIV>
