Re: Bar chart with 2 y-axis?

Hi Gina,

Just in case you *are* doing paneling, you can actually do this with
this type of bar chart. See the last example (#11) on the bar chart

http://www.ncl.ucar.edu/Applications/bar.shtml

Adam is the one who created the original single plot example, and I
have to say I was impressed with how he did it.
