[ncl-talk] 2nd y-axis label plus...

Tue May 26 07:15:23 MDT 2015

Hi Mary,

The example solution in #19 solved the problem.
The plots needed to brought closer so that the right titles
could be seen. The results look great now.
Thanks a lot!

Do you still need me to send you the data?

Setting resP at gsnPanelDebug to True will print the default values being used for the x position, allowing you to adjust as necessary.

It would really help if you could provide us with the data so we can run your script, or else provide us with a small test case that illustrates the problem.
