An abstract base class used to group together its derived types, providing the symbology of a feature layer.
A Feature renderer defines a set of symbols that will be used for drawing feature layers. The feature renderers use symbols and colors to visually display features, possibly based on one or more attributes.
The followings are types of feature renderers:
- SimpleRenderer uses the same symbol for each feature
- ClassBreaksRenderer allows classes of numeric attribute values to be defined. A different symbol is specified for each class. The symbols typically vary in either color or size. This renderer can be used for ordinal, interval, or ratio data.
- UniqueValueRenderer uses a different symbol for each unique attribute value. A value can come from a single field or a combination of more than one field. This is used for nominal data.
