Hi Tabish,
I think *"gsnPanelYWhiteSpacePercent" *is a panel resource and should be
added in your panel resource list (i.e. resP), try the following:
resP@*gsnPanelYWhiteSpacePercent* = 2
There are other possible ways of reducing space between the plots, for
example, using view point resources:

Cheers,
Rashed
