[ncl-talk] Does gsnRefLine change the data?

[Rick Brownrigg]

This is quite odd indeed. It appears that with the y-ref line enabled, an
additional channel of data is plotted along with the data from the 1st plot
(?)

Are you able to share you script and data?  You can send it directly to me
if you prefer.
