<div dir="ltr">Thanks Mary and David. Mary's suggestion solved my font size issue.<div><br></div><div>I have a follow-up question I'm hoping you can help me with. I'd like to make the color lines within the legend the same actual length (e.g. as measured in inches on paper) regardless of the length of the longest legend label (text). Also, I'd like to make the distance from the left edge of the legend box to the start of the lines the same physical distance, again regardless of the lengths of the legend labels.</div><div><br></div><div>What I'm trying to do is to have a legend that only changes on its right side when I have longer legend labels (by having the legend box width extend only to the right to accommodate the longer label(s)). I'd like the left portion of the legend (where the lines are) to stay exactly the same in terms of the positions and physical dimensions of the various items. </div><div><br></div><div>I modified my previous code (see attached test_legend2.ncl) to try out some cases, but I haven't been able to get things to work yet. When I have labels that aren't too long, the legend lines are, as expected, a factor lgBoxMinorExtentF of the width of the legend box (test_legend_short_label.png), but when they are long, the legend lines get squished to some factor smaller than the specified lgBoxMinorExtentF (test_legend_long_label.png).</div><div><br></div><div>I'd appreciate any suggestions on how to solve this issue. </div><div><br></div><div>Thanks again,</div><div>Gerard</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Sep 16, 2015 at 11:32 AM, David Brown <span dir="ltr"><<a href="mailto:dbrown@ucar.edu" target="_blank">dbrown@ucar.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I will look into this question.<br>
