Re: Multiple Fill Palettes and PDF/PS

(Curious -- gsn_panel_return() seems to be undocumented!)

I'm guessing you are using NCL6.1.0? I can't tell for certain what is going on, but reading through the code and the reported line numbers, there is some PS/PDF-specific code getting invoked. In particular, there's some internal code that determines plot size and dimensioning details, and it uses the 1st plot in an array of plots to get "parent object" information.

In the code snippets you included, from line 499, that array of plots would be your array "plot2", and it looks like the 1st 3 elements of that are undefined (?), and I'm guessing this to be the source of the error.

This may be a bug in 6.1.0, as the docs (for gsn_panel(), a similar function) state: "If any of the plots are missing, then the location where the plot would normally be will be blank." It also looks like perhaps it has been fixed in NCL-6.2.0.

I hope that helps...
