I'm learning MapServer so my expectations for what it does may be
incorrect.<br>
<br>
I want to assign a color to some features from a database based on a
field. The full range of values is large, so I don't want to code a
CLASS for each value. Instead I'd like to use an expression for the
color.<br>
<br>
For example, if the attribute of a feature ranges from 0 to 1000, I'd
like to use it to drive a range of the color green:<br>
<br>
LAYER<br>
DATA "the_geom from myFeature"<br>
CLASSITEM "col1"<br>
TYPE LINE<br>
...<br>
CLASS<br>
NAME "myFeature"<br>
STYLE<br>
COLOR 0 ([col1] / 1000 * 255) 0<br>
WIDTH 1<br>
END<br>
END<br>
END<br>
<br>
Thanks<br>
