Thanks Muhammad,<br>
this actually works if I display wind;vw<br>
But again, if I use "wind" in a define expression, it doesn't go
well.<br>
<br>
define arrows = wind;vw<br>
<br>
<div>Syntax error: expected operator or ')'</div>
<div>Error occurred at column 23<br>
</div>
<br>
Now, I would really need to define this quantity because I'm going
to use it later. Is there a way to do that?<br>
<br>
Thanks for your help.<br>
Stefano<br>

<div>Hi everyone,</div>
<div>I am using Grads 2.0.0.oga.1 and I am facing an odd issue.</div>
<div>When I try to define an expression for plotting wind vectors in this way:</div>
<div>define wind=skip(uw,8,8);vw</div>
<div>(where uw and vw are the two horizontal components), I get the following </div>
<div>error:</div>
<div>Syntax error: expected operator or ')'</div>
<div>Error occurred at column 23</div>
<div>Grads displays wind arrows in a proper way, instead, when I plot the </div>
<div>expression directly:</div>
<div>d skip(uw,8,8);vw</div>
<div>Bets regards,</div>
<div>Stefano Materia</div>
