[OpenLayers-Users] How to create legends for WMS Layers

[Rahn Hanno (rahn)]

Hello list,

I try to show a legend for my base WMS layer. But I don't know how to realsie it. Is there a possibility in OpenLayers to show a legend in a div?
I want to have a legend like this:

0 - 0.5
>0.5 - 1
>1 - 2
>2 - 3
>3 - 4

I know the GetLegendGraphic Parameter for WMS, but if I use this my legend always looks like this:

0 - 0.5
0.5 - 1
1 - 2
2 - 3
3 - 4

But with this you don't know which is the class for 0.5. Is there a dynamic way to create the legend, My data is in an postgres database and I use UMN Mapserver for the WMS.

Thank you
Hanno
