DataLabelsFilter (The ZK Charts library 11.2.0.0 API)

java.lang.Object
- org.zkoss.chart.Optionable
- - org.zkoss.chart.plotOptions.DataLabelsFilter

All Implemented Interfaces:

Serializable, OptionDataListener, org.zkoss.json.JSONAware
```
public class DataLabelsFilter
extends Optionable
```
A declarative filter to control of which data labels to display. The declarative filter is designed for use when callback functions are not available, like when the chart options require a pure JSON structure or for use with graphical editors. For programmatic control, use the formatter instead, and return undefined to disable a single data label.

7.2.1.0
