Thanks for the reply. If I union the axes, the individual panels are no longer lined up correctly (they are showing different ranges within the dataset even though they look aligned in the resulting figure - hence the different view min/max for each panel).    For now at least, I may have found a workaround by setting the row weights to make each panel take up the same amount of space.  ...

That is correct, if you look in Dictionary.Columns table it always stores the libname and memname in upper case letters. Happy to hear your issue is resolved. A somewhat safer method in the long run is to up case your comparison all the time, but that can add some extra time to the query. libname = upper('WORK') and memname = upper('MEANCPUABOTTOMFISH'); ...

Could you consider "block" as a spatial co-ordinate based on the centroid of the area?  Then a spatial analysis with boat as the subject could be explored.   It would probably mean using a mixed model approach with sample weighting because this is a survey rather than a designed experiment, and a two-dimensional spatial covariance type would be needed, so you may be in some rough waters (no pun intended there).   You may want to look at some of the ecology literature on analysis of this type.  I know that field has a strong R preference, but similar models can be constructed in SAS.   SteveDenham ...
