[ncl-talk] Label a polyline

[Wei Huang]

Mary and Dave,

In example: https://www.ncl.ucar.edu/Applications/Scripts/xy_14.ncl
Where we can draw a line and label it:

If I have a isoline info, (lat, lon) info, I can draw a polyline:

plines(n) = gsn_add_polyline(wks, plot, lon, lat, res)

If I know the value of the above isoline/polyline,
How can I add a label similar to xy_14 to this polyline?

Or how can I get the similar labeled line?

Thanks,

Wei Huang
