Hi,
You can't with the UI, but :
- you can approximate it with colored array by displaying overlay, (may need OpenGL)
- or modify directly opencpn configuration file: on linux opencpn.conf , opencpn.ini on window. Search for :

[PlugIns/GRIB]

or

WavesUnits=

and add

WavesDisplay\ Isobars=1  
WavesIsoBarSpacing=0.5

Use whatever you want for WavesIsoBarSpacing, here I'm using half a meter.



Caveat :
- you may have to redo it if you change something with the UI.
- Opencpn is not very robust if its configuration file is bogus and it's likely to die, so backup this file before doing any change.

Okay, I try it. Thank you
