<div dir="ltr"><div class="gmail_default" style="font-size:small">Hi Emanuele,</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">The labelbar is admittedly hard to control sometimes. When you turn on a labelbar for a plot (versus creating from scratch yourself), the plot is trying to control some features of it so that the width, height, and the labels are sized relative to the plot.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">If you need to have a fixed labelbar size, then I suggest creating the labelbar yourself from scratch using. This can be a bit of a pain, but once you have it, you can use the code over again for other plots. Also, we have lots of examples to help you with this.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">As a start, see "lb_19.ncl" at</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small"><a href="http://www.ncl.ucar.edu/Applications/labelbar.shtml#ex19">http://www.ncl.ucar.edu/Applications/labelbar.shtml#ex19</a></div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">which you should be able to download and run as-is. It shows how to recreate a labelbar from a given plot (see the "contour_labelbar" procedure).</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">You could try this procedure and see if it gives you the labelbar you want. You can also modify the procedure to override any labelbar settings to whatever you want. For example, you can change the width and the height by changing these two lines:</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small"><div class="gmail_default"><font face="monospace, monospace">;---Set width and height of labelbar itself </font></div><div class="gmail_default"><font face="monospace, monospace"> lbres@vpHeightF = lbar_h</font></div><div class="gmail_default"><font face="monospace, monospace"> lbres@vpWidthF = lbar_w</font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif"><br></font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif">To control the location of the labelbar, change these two values:</font></div><div class="gmail_default">
<p class=""><font face="monospace, monospace">lbar_x<br>lbar_y</font></p><p class="">and so on. If you have any trouble with this procedure, please post back to ncl-talk and let us know.</p><p class="">Good luck,</p><p class="">--Mary</p></div></div><div class="gmail_default" style="font-size:small"><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Mar 13, 2016 at 12:41 PM, Alan Brammer <span dir="ltr"><<a href="mailto:abrammer@albany.edu" target="_blank">abrammer@albany.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word"><div>Without seeing an actual NCL script and how you’re plotting it’s hard to guess. </div><div>But have you looked at the label bar examples? </div><div><br></div><div>Initial resources you could set, taken from lb_5.ncl <a href="https://www.ncl.ucar.edu/Applications/labelbar.shtml:" target="_blank">https://www.ncl.ucar.edu/Applications/labelbar.shtml:</a> </div><div><pre style="word-wrap:break-word;white-space:pre-wrap"><pre style="word-wrap:break-word;white-space:pre-wrap"> res@pmLabelBarWidthF = 0.4 ; default is shorter
