Setvalues will simply change the resource value of an existing object, and the legend manager doesn't enter the picture and try to shrink your labels.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">It's a kludge, but I think it should work. here's what the old code looks like:</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small"><div class="gmail_default"><div class="gmail_default"><font face="monospace, monospace"> gsn_legend_ndc(wks_png, num_curves, legend_labels, 0.20, 0.35, lgres) </font></div><div class="gmail_default"><div class="gmail_default"><font face="monospace, monospace"> frame(wks_png)</font></div><div><font face="monospace, monospace"><br></font></div><div><font face="arial, helvetica, sans-serif">And here's what the new code should look like:</font></div><div><font face="arial, helvetica, sans-serif"><br></font></div></div><div class="gmail_default"><font face="monospace, monospace"> ;---gsn_create_legend creates the legend, but doesn't draw it </font></div><div class="gmail_default"><font face="monospace, monospace"> legend_id = gsn_create_legend(wks_png, num_curves, legend_labels, lgres)</font></div><div class="gmail_default"><font face="monospace, monospace"><br></font></div><div class="gmail_default"><font face="monospace, monospace">;---Reset lgLabelFontHeightF to the desired value</font></div><div class="gmail_default"><font face="monospace, monospace"> setvalues legend_id<br></font></div><div class="gmail_default"><font face="monospace, monospace"> "lgLabelFontHeightF" : lgres@lgLabelFontHeightF</font></div><div class="gmail_default"><font face="monospace, monospace"> end setvalues</font></div><div class="gmail_default"><font face="monospace, monospace"><br></font></div><div class="gmail_default"><font face="monospace, monospace">;--Now draw the legend</font></div><div class="gmail_default"><font face="monospace, monospace"> draw(legend_id)</font></div><div class="gmail_default"><font face="monospace, monospace"> frame(wks_png)</font></div><div><br></div><div>You may need to place with lgres@vpXF and legres@vpYF to position the legend as desired.</div><div><br></div><div>--Mary</div><div><br></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Sep 14, 2015 at 11:19 PM, Gerard Ketefian - NOAA Affiliate <span dir="ltr"><<a href="mailto:gerard.ketefian@noaa.gov" target="_blank">gerard.ketefian@noaa.gov</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hi,</div><div><br></div><div>I'd like to generate a legend in which the font size of the item labels is the same regardless of the length (i.e. the number of characters) of the item labels.

According to the online documentation, in this case NCL should not adjust the font size, and I should get whatever font size I specified via lgLabelFontHeightF.
