<div dir="ltr"><div>Tabish, I am glad that you got it working. The default text function code was changed from <b>":"</b> to <b>"~"</b> in recent versions of NCL, and it looks like you are using the new default. The cited example set the older text function code explicitly: <b>txres@txFuncCode = ":"</b></div><div><br></div><div>I recommend <b>~F34~1~F~</b> rather than <b>~F34~1~F21~</b> so that the left and right sides of your output string will use exactly the same font.
