Most feature layers can store attribute field values with relevant information for each of their features, such as population, land use, or zoning code. This information can be used to control the appearance and behavior of layer features based on field attribute values. For example, you can represent the number of people living in a country by the line color of the country's boundary. When basing a property field on an attribute field, you must establish the property you want to set, and the attribute field on which to base your setting.
There are four types of properties that can be set based on attribute fields:
- Color properties such as line color and fill color.
- Numeric properties such as building height or text label altitude.
- The text content of text labels, tooltips and other text elements.
- Drop-down lists properties such as font size or text underline.
There are three types of attribute fields that properties can be based on:
- Textual attribute field types e.g., land use.
- Integer attribute field types - Stores whole numbers without any decimals. e.g., number of people in household.
- Double attribute field types Stores real numbers having a double precision floating point. e.g., average income.
