+ RANGEITEM [attribute]
+
+
+ Specifies the attribute that will be used to
+ map colors between the high and low ends of the
+ COLORRANGE entry. Colors are mapped to a
+ continuous linear gradient between the two values.

+
+ Here is an example mapping the values 0.0-1.0
+ to RED-GREEN.

+ COLORRANGE [r] [g] [b] [r] [g] [b]
+
+
+ Defines two colors to correspond to the low
+ and high ends of the DATARANGE values. Colors are
+ mapped to a continuous linear gradient between the
+ two values.

+
+
+
+ DATARANGE [lowValue] [highValue]
+
+
+ Defines two values that mapserver will map to
+ the color range defined by the COLORRANGE entry.
+ Values must be constants that evaluate to an
+ integer or floating point decimal. Colors are
+ mapped to a continuous linear gradient between the
+ two values.
