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.

- series - Defines the series of this definition.
- definition - Defines the class that implements org.eclipse.birt.chart.datafeed.IDataPointDefinition. A datapoint definition is responsible for defining the data types of a datapoint entry and the display text.

###### Examples:

###### API Information:

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

###### Supplied Implementation:

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.
