<div dir="ltr">You can also thin vectors by subsampling or
"striding" the data grid. I have used this method with good
results. This is somewhat different than the effect with
vcMinDistanceF. The subsampling method gives explicit
control over which rows and columns are plotted. See and
compare both methods in example 4 on the Vector Effects
page:</div>

<div>1) Set vcRefAnnoString2 = "Vector" or ""</div>

<div>2) tiXAxisOffsetYF = 0.05 ; you will likely
have to try different settings to get the exact
positioning you want</div>

<div>3) The best option is usually to set
vcMinDistanceF. See example #3 here:</div>

NCL community,<br>
<br>
Three questions for a overlay(contour, vector) plot:<br>
<br>
(1) How to make "Reference Vector" in legend's
upperright side as <br>
"Vector" or nothing?<br>
<br>
(2) How to make Longitude (X axis title) higher than
colorbar of contour <br>
T2？<br>
<br>
(3) How to make the CurlyVector less dense?<br>
<br>
Thanks in advance,<br>
<br>
