<DIV>Maybe this?</DIV>
<DIV> </DIV>
<DIV>If you want to display the speed as a color on the vector</DIV>
<DIV> </DIV>
<DIV>set gxout vector</DIV>
<DIV>d u ; v ; mag(u,v)</DIV>
<DIV>cbar</DIV>
<DIV> </DIV>
<DIV>Or if you want a shaded map of colors behind the vectors</DIV>
<DIV>set gxout shaded</DIV>
<DIV>d mag(u,v)</DIV>
<DIV>cbar</DIV>
<DIV>set gxout vector</DIV>
<DIV>d u ; v</DIV>
<DIV> </DIV>

I think that this is some bug. <BR>> <BR>> HELP! <BR>> <BR>> :) <BR>> <BR>> Angel <BR>> <BR>> <BR>> ===== <BR>> Angel Dimitrov <BR>> Varna, Bulgaria <BR>> http://www.stormlab.net <BR>> http://www.stormlab.tk <BR>> http://www.vveather.tk <BR>> <BR>> <BR>> <BR>> <BR>> __________________________________ <BR>> Do you Yahoo!? <BR>> Yahoo!
