Hi-
I have a script that has been running fine under NCL 6.1.2, but now is
not acting the same under 6.2.0. The part that isn't working is drawing
a polyline along the equator. The relevant code is:
plot = gsn_csm_contour_map(wks,data,rescf) ; color-filled
if (.not.isanom) then
plot1 = gsn_csm_contour(wks,data,rescn) ; contours
overlay(plot,plot1)
end if
dlin = gsn_add_polyline(wks,plot,(/180,180/),(/-90,90/),resp) ; dateline
equa = gsn_add_polyline(wks,plot,(/0,360/),(/0,0/),resp) ; equator
draw(plot)
draw(lbid)
gsn_text_ndc(wks,"NOAA/ESRL/PSD",0.088,0.190,restx)
if (isanom) then
gsn_text_ndc(wks,"Base Period: "+baseDateString,0.52,0.190,restxa)
end if
frame(wks)
In this script, a line is drawn at the dateline and the equator:

Since upgrading to NCL 6.2.0, the equator line is missing:

If I print out the data summary, it looks like:
Variable: data (parameter)
Type: float
Total Size: 259200 bytes
64800 values
Number of Dimensions: 2

standard_name : sea_surface_temperature
_FillValue_original : 32767
_FillValue : 32767
valid_range : ( -5, 40 )
missing_value : 32767
I tried adjusting the x values to be (/1,359/), but still no line across
the plot.
Thoughts on what could be going wrong?
