<div dir="ltr">Hi Bingxue,<div>To search the ncl-talk archives you can simply enter your search term in the search bar on the NCL website. </div><div><br></div><div>There is no way to create a reference vector similar to that created using the gsn*vector plotting routines when you are using the wmvect procedures. If you want the reference vector to look like it does for the gsn*vector routines, I believe you have three choices:</div><div>1 - Use gsn_polyline_ndc/gsn_text_ndc to draw the vector/label yourself.</div><div>2 - Use Illustrator or similar software to add the vector/label outside of NCL.</div><div>3 - Call gsn_csm_vector to draw a blank vector field and blank plot by setting the vector color to the background (white), turn off all the borders of the plot (tmXBBorderOn = False for example), turn off the tickmarks (tmXBOn = False), and draw the plot with the customized reference vector set using the resources you cited. This is the most tedious option, but it is possible. </div><div><br></div><div>Hopefully that at least gets you going in the right direction. If you have any further questions please respond to ncl-talk.</div><div>Adam</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Nov 27, 2019 at 2:54 AM 吴冰雪 via ncl-talk <<a href="mailto:ncl-talk@ucar.edu">ncl-talk@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="line-height:1.7;color:rgb(0,0,0);font-size:14px;font-family:Arial"><div><pre style="width:1117.19px;line-height:23.8px">Dear All, </pre></div><div> The example I have found in the NCL website(as following shown) by using the wmvect and wmvlbl function,the reference arrow legend is special(like 0.35E+2and the length of the reference arrow is constant by using wmvlbl function ),which isn’t what I want,.</div><div> I just wonder if any way the reference arrow legend it could be the same look like use res@vcRefMagnitudeF and res@vcRefLengthF.</div><div><img src="cid:16ed354927dcb971f161" style="width: 128px; height: 64px; border: 1px solid rgb(153, 153, 153);">(this is not what I want)<img src="cid:16ed354927dcb971f162" style="width: 74px; height: 40px; border: none;">(this is what I want)</div><div>NCL website : <a href="http://www.ncl.ucar.edu/Applications/weather_sym.shtml" target="_blank">http://www.ncl.ucar.edu/Applications/weather_sym.shtml</a></div><div><a href="http://www.ncl.ucar.edu/Applications/Scripts/weather_sym_8.ncl" style="margin:0px;padding:0px;text-decoration-line:none;color:rgb(133,45,133);font-family:verdana,sans-serif;font-size:13.3333px" target="_blank">weather_sym_8.ncl</a></div><div><a href="http://www.ncl.ucar.edu/Applications/Scripts/weather_sym_8.ncl" style="margin:0px;padding:0px;text-decoration-line:none;color:rgb(133,45,133);font-family:verdana,sans-serif;font-size:13.3333px" target="_blank">weather_sym_9.ncl</a></div><div><div style="line-height:23.8px"><br></div><div style="line-height:23.8px"><br></div><div style="line-height:23.8px">Thank you !</div><div style="line-height:23.8px"><br></div><div style="line-height:23.8px">At last, if anybody can tell me how to search the mail list before.
