The colour scale range is set per-variable, not per-dataset. The only sensible way I can see for a sysadmin to configure this accurately would be within the TDS catalog in NcML, for example:
<variable name="temp"> <attribute name="defaltColorScaleRange" value="-5.0 35.0"/> </variable>
(If we agreed on a syntax for this it would be an easy change in the WMS code I think.)
It might also be possible to provide a global set of defaults per CF standard name in a configuration file for variables that don't define a range explicitly.
What do others think?
1. what does ncWms currently do for default? Use data min/max?
2. Rich, what would a hand-configured option typically do?
