IPPSpeedometerArrowBase.Background

Syntax

Background: IGxBrush;

Description

The Background property determines a brush for arrow background fill.

Comments

The Background property is relevant if the IPPSpeedometerArrowBase.EnableBrush property is set to True.

Example

Executing the example requires that the repository contains a database with the ADHOC identifier. A dashboard must contain a speedometer.

Add links to the Adhoc, Drawing, Express, Metabase, Speedometer system assemblies.

After executing the example parameters of speedometer data scale arrow are set up.
