|
This example uses four rules to render features. Rules are
|
|
based on a feature attribute and determine which symbolizer
|
|
is applied when rendering a feature. The rules in this example
|
|
change which marker is used by providing an externalGraphic
|
|
property in the symbolizer.
|
|
</p>
|
|
The features are labeled with the same attribute that determines
|
|
the symbolizer used. You should be able to confirm that the
|
|
graphic color corresponds to the range of numbers given below.

<ul>

<li>0 <= blue < 25
|
|
<li>25 <= green < 50
|
|
<li>50 <= gold <= 75
|
|
<li>75 < red <= 100
