Hi Adam,
<div class=""><br class="">
</div>
<div class="">thank you for the reply. </div>
<div class=""><br class="">
</div>
<div class="">However, even setting the resource I don’t get rid of the tiny vectors. Below the resources I set for vector plot</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">
<div class=""> res_vc = res</div>
<div class=""><br class="">
</div>
<div class=""> res_vc@vcRefMagnitudeF = 20. ; define vector ref mag</div>
<div class=""> res_vc@vcRefLengthF = 0.01 ; define length of vec ref</div>
<div class=""> res_vc@vcRefAnnoArrowLineColor = "black" ; change ref vector color</div>
<div class=""> res_vc@vcRefAnnoArrowUseVecColor = False ; don't use vec color for ref</div>
<div class=""> res_vc@vcGlyphStyle = "CurlyVector" ; turn on curly vectors</div>
<div class=""> res_vc@vcLineArrowColor = "white" ; change vector color</div>
<div class=""> res_vc@vcLineArrowThicknessF = 2.5 ; change vector thickness</div>
<div class=""> res_vc@vcVectorDrawOrder = "Draw" ; draw vectors last</div>
<div class=""> res_vc@tfDoNDCOverlay = True</div>
<div class=""> res_vc@vcMinDistanceF = 0.017</div>
<div class=""> res_vc@vcMinFracLengthF = 0.0</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>res_vc@vcMinMagnitudeF = 300.</div>
</div>
<div class=""><br class="">
</div>
<div class="">any thoughts?</div>

<div class="">thanks!</div>

<div style="word-wrap:break-word;line-break:after-white-space" class="">Dear helpdesk,
<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>
