[idvdevelopers] converting units

[Stuart Maclean <stuart@xxxxxxxxxxxxxxxxxx>]

I am am reading a netcdf model grid into a GeoGrid, and then on via a  
GeoGridAdapter into a IDV Displayable object.  My data is t,y,x ->  
temperature, where the raw values are in Kelvin.

I am using IDV's TextDisplayable to do an IDV like 'Value Plot'.  I  
would like to display some other unit, i.e Celsius, for the text values.

I suspect there is a very simple way to do this, I just cannot find it  
in the javadocs ;)

A brute force way would be to construct a new FlatField, populate its  
domain with that from the original, build a new realType for  
tempCelsius and scale over from the original tempKelvin, and use the  
second FlatField for the TextDisplayable...

Any help appreciated
