<div class=""><br class="">


</div>


<div class="">I am trying to plot velocity vectors over a contour (+other stuff, see attached pdf).</div>


<div class=""><br class="">


</div>


<div class="">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 class=""><br class="">


</div>


<div class="">If I try to mask the u/v variables, I get an error. </div>


<div class=""><br class="">


</div>


<div class="">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 class=""><br class="">


</div>


<div class="">thanks!</div>
