Classification by Attributes
Classification is grouping similar features into classes to organize your data more efficiently. You can modify the display of a layer based on the values of its attributes. Those values can be distinct or continuous. To make the classification process as easy as possible, you can use our Wizard to help you with expressions. However, every class can be modified to suit your needs, so you can manage expressions manually as well.
The classification tool can be found in the Appearance section on the bottom of the Layer Properties. To open Layer Properties, double click on the layer in a Layer List or click on Edit Layer in Layer tab.
