Roopa,<br>Use a third argument when displaying your vectors that will actually be colored. In your case do "display uwind;vwind;mag(uwind,vwind).<br><br>Hope this helps.<br><br>Jeff Duda<br><br><div class="gmail_quote">

<div>Dear all,</div>
<div> can anyone please tell me how to color vectors by magnitude in a grads plot. If I change the color using set ccolor command then uniformly all the vectors get changed to the new color. i don't want that. A smaller magnitude should show a given color and a larger magnitude some other color etc. </div>

<div>thanks is advance</div>
