<div>Hi Rick</div>
<div><br>
</div>
<div>Thanks for your fast answer.</div>
<div>Attached I’m sending you a screen-shot.</div>
<div>I just want to decrease the length of the dash paterns in the legend. It looks kind of silly when they are so long. I tried to draw the desired outcome 😃</div>

<div>I wnat to draw a legend for my xy-plot in ncl, but the dash patern of the line is very long compared to the text. I tried to make the dash pattern shorter with lgLineDashSegLenF but it did not work. How can I controll the length of the dash pattern using
the legendClass?</div>
