BorderWidth: Double;
The BorderWidth property determines marker border width.
The BorderWidth property is relevant if the IPPSpeedometerMarkerBase.EnableBorder property is set to True.
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 speedometer marker parameters are set up.
