This would generally be done as a Ferret property for each variable, though if you had a dataset whose variables all have similar ranges, it could be a Ferret property applying to the whole dataset. This might look something like this: <variables> <RAIN-id-60f7e24b64 name="rainfall" units="mm" url=""> <link match="/lasdata/grids/grid-LONGITUDE-LATITUDE-TIME-id-60f7e24b64" /> <properties> <ferret> <fill_levels>(0,75,5)(75,155,10)(inf)</fill_levels> </ferret> </properties> </RAIN-id-60f7e24b64> Which would use similar levels to what is automatically computed, but always starting at zero. It still keeps an open-ended level at the top. If you want to set up your own levels for an anomaly, (-inf) is used to specify an open-ended level at the lower end of the scale. You could also use just a linear scale such as <fill_levels>(0,160,10)(inf)</fill_levels> Or any other Ferret specification for LEVELS, which are discussed in the Ferret documentation, http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/customizing-plots/CONTOURING#_VPINDEXENTRY_852
