[ncl-talk] Fwd: error bars not showing up on xy scatter plot

[Anne]

Dear NCL users,

I am trying to add y-"error" bars to a scatter plot that for each data
point should represent the standard deviation of the members. I am trying
to follow example 13 here:  https://www.ncl.ucar.edu/Applications/xy.shtml
, using polylines. However those bars/lines don't show up in my plot. Do I
miss something?
I am using NCL version 6.4, and I attach the plot and the script (adding
the polylines is the last part of the script).

Thanks for any help,
Anne
