<div style="word-wrap:break-word;line-break:after-white-space">Dear helpdesk,
<div><br>
</div>
<div>I am trying to plot velocity vectors over a contour (+other stuff, see attached pdf).</div>
<div><br>
</div>
<div>I have a question, is there a way to mask out the small vectors and leave only velocity vectors exceeding some threshold (let’s say 100 m/yr)? </div>
<div><br>
</div>
<div>If I try to mask the u/v variables, I get an error. </div>
<div><br>
</div>
<div>Looking on the internet, I see that there is someone suggesting to overlay two vector contours, but the procedure seems to be a little bit complicated, and I wonder if there exists a simpler way,..</div>
<div><br>
</div>
<div>thanks!</div>
<div>Michele</div>
