[ncl-talk] Forgot to post script - Panelling & plot sizes

[Adam Phillips]

Hi Juris,
A good debugging process to use on this situation is to simplify your
resource list, identify the source of the issue, and then add resources
back in. In this case, I would start by simplifying your panel resource
list, specifically your res_bar list. I would start with removing the
following resources:
res_bar at pmLabelBarHeightF = 0.20
res_bar at gsnPanelScalePlotIndex = 2

The first of those resources is setting the label bar height to be 20% of
the height of the page which is likely too big. (panel_33 uses vertical
label bars thus a setting of .20 would be appropriate in that case.) The
second resource is telling NCL to use the size of the 2nd plot as the
proper size, but the resource (like-ncl) is zero-based and you only have
plot_bar(0) and plot_bar(1).

Finally, I would also alter this resource setting:
res_contour at gsnPanelBottom = 0.25
to something like this:
res_contour at gsnPanelBottom = 0.35

as I believe the label bar does not count as part of the panel boundary,
and thus drops below your original setting of 0.25.

Hope that helps. If not, please respond back to the ncl-talk email list.
Adam
