Re: [mapserver-users] Color ramps with polygons vs raster

Can you give a polygon file (values 1 - 50) a graduated color ramp using
a class expression?

more or less, this works:

CLASS
  NAME 'roads'
    STYLE
      WIDTH 3
      COLORRANGE 0 0 255 255 0 0   #color start RGB and end RGB
      DATARANGE 0 50  #the data range is normally set to the class expression 
range
      RANGEITEM "maxspeed" # maxspeed­value in osm­dataset
    END
  END
