JRChartCustomizer (JasperReports Library 6.20.2 API)

All Known Subinterfaces:

NamedChartCustomizer

All Known Implementing Classes:

JRAbstractChartCustomizer
```
public interface JRChartCustomizer
```
This interface allows users to provide pluggable chart customizers. A class that implements this interface can be defined and its name must be specified in the report template. At fill time, the corresponding customize() method of this class will be called, if advanced chart customization is needed.
If values of report parameters, variables or fields are needed in the customization, the customizer implementation should extend JRAbstractChartCustomizer to gain access to such values.
