|  | ## Register Visualization from Database

#### Synopsis

Allows the visualization of examples (attribute values) in the plot view of an example set (double click on data point). The data is directly derived from the specified database table.

#### Description

Queries the database table for the row with the requested ID and creates a generic example visualizer. This visualizer simply displays the attribute values of the example. Adding this operator is might be necessary to enable the visualization of single examples in the provided plotter or graph components. In contrast to the usual example visualizer, this version does not load the complete data set into memory but simply queries the information from the database and just shows the single row.
