Data(elId: String): Variant;
elId. Identifier of the element, the value of which is to be obtained.
The Data property returns the value of selected element.
To determine a data source, use the IVZDataSourceMapping.DataSource property.
Executing the example requires that the repository contains an express report with the EXPRESS identifier, which data source is built on a dictionary with the TBL_DICTIONARY identifier. The Color metric should be selected in the bubble tree report.
Add links to the Drawing, Express, Metabase, Visualizators system assemblies.

Debug.WriteLine("Index, by which data from each dimension is returned: " +

Before executing the example, the color scale of bubble tree looks as it is shown on the IVZDataScale interface description page.
After executing the example, the following will be set:
Identifiers of data source, dimension, by which data is selected.
Fill color for the "no data" bubble.
After executing the example the console window displays data source name and identifier of the dimension, by which data is selected.
