[ncl-talk] sfYCStartV and sfYCEndV

[David Bailey]

Thank Rick. I had been thinking later that I could rebin my data so that it
would have a regular Y axis and then fill with missing values. This however
seems like a lot of extra work. I would have to average into the bins and
it would be ugly. I can probably live with the different Y axis in each
plot.
