A datapoint definition extension point specifies a mapping entry between a datapoint definition name against the definition implementing class name. Note that all datapoint definition implementations must implement org.eclipse.birt.chart.datafeed.IDataPointDefinition. A datapoint definition is responsible for defining the data types of a datapoint entry and the display text.



Please refer to the javadocs for IDataPointDefinition in the org.eclipse.birt.chart.datafeed package.

Only the series that wants custom display of data point needs to implement the interface org.eclipse.birt.chart.datafeed.IDataPointDefinition and register it with extension point.
