TCustomDBChart.OnProcessRecord
TCustomDBChart
property OnProcessRecord: TProcessRecordEvent;
Unit
DBChart
Description
An OnProcessRecord event occurs for each record that is retrieved from the database.
The TDBChart component triggers this event whenever a new point has been added to the Series.
The DataSet parameter is the database component ( Table, Query, etc ) from which records are being loaded.
You can raise an Abort silent exception in this event to notify TDBChart to stop retrieving records and to NOT add the current record point.
