A Custom Expression Filter lets you set up a group of different expressions which can be used to filter data. These expressions can be represented as a button bar, or as a drop-down. Each expression shows up as an individual item in the pull-down, or as its own button.

The user interface is comprised of a list of expressions, which can be reused throughout the system.
Each expression can be written independently, and can compare as many columns as necessary. The following example below shows a filter expression that examines values in two different attributes using the AND operator.
Each expression is associated with its own renderer. The renderer supports the following properties:
When applying a Custom Expression Filter to a Visualization, the administrator can decide how much of the configured renderer to show based on available real estate.
