[netcdfgroup] netcdf - how to add a legend

[Ana <rrasterr@xxxxxxxxx>]

Hi!

I am using THREEDDS data server and we have the IDV, NetCDF-Java and
Godiva2 for Viewers.

The datasets are grid feature types and I would like to know how can I add
a legend (to attribute a name to each value and a colour).



Thanks in advance.

Regards,
Ana
