How do you format the legend in Geoserver when using GetLegendGraphic?

Question

I'm new to the world of GIS and geoserver so sorry if I'm asking an obvious or simple question.

I'm using GetLegendGraphic to create a legend for a raster layer on the server, as it stands it looks like this:

http://norsewind.eu:8080/geoserver/wms?REQUEST=GetLegendGraphic&FORMAT=image/png&WIDTH=20&HEIGHT=20&SCALE=160000000&LAYER=norse:norse_map_1

I'd like to know how to format the numbers to a specific number of decimal points. Also I don't need the '=x' part, can that be removed?

Thanks

Answer 1

The text parts are controlled in the SLD colormap label, ie

    <ColorMapEntry color="#FFFF00" quantity="0.25" label="0.25"/>

I don't think either of your questions can be handled from the GetLegendGraphic request.
