legend generation

[Eijnden, Bart van den (AGI)]

You need to use NAME instead of TITLE in the CLASS definition.

E.g.:

     CLASS
       EXPRESSION (([HUISNUMMER]^2 <= 4) OR ( [HUISNUMMER]^2=9 ))
       METADATA
       END
       STYLE
         ANGLE 360
         COLOR 255 0 0
         SYMBOL 2
       END
       NAME "huisnummer <= 3"
     END

Hi People,

I don't understand legends I think. I have found the mapfile reference 
and mapscript API reference, but can't get this to work.
I have got a map file (see below). When I try to create a legend for it 
with the mapserver legend tool, or by using mapscript 
(someMapObj.drawLegend().save(filename)), I only get a very small empty 
image. The map itself is displayed correctly with blue and red points. 
What is needed to create a legend. What am I doing wrong? I don't know 
where to look.
Thanks,

Dolf.
