<div dir="ltr">Hi LSL,<div>I wonder if the legend text is being drawn but is off of the plot. Try shifting the position of the legend by setting pmLegendParallelPosF = 0.1.

<div>Thanks for the help from Dennis and
Adam. Now there is no complain on the screen after executing the
ncl script, but there is still no lgLineLabelStrings beside the
line on the figure.</div>
