public class Chart
extends Imagemap

The generic chart component. Developers set proper chart type, data model, and the threeD (3D) attribute to draw proper chart.

Chart requires an implementation of an engine (ChartEngine). The default engine is based on JFreeChart and available in ZK PE and ZK EE.

The model and type must match to each other; or the result is unpredictable. The 3D chart is not supported on all chart type.

  - getEngine
```
public ChartEngine getEngine()

```
    Returns the implementation chart engine.
    
    Throws:
    
    org.zkoss.zk.ui.UiException - if failed to load the engine.
  - newChartEngine
```
protected ChartEngine newChartEngine()
                              throws org.zkoss.zk.ui.UiException
```
    Instantiates the default chart engine. It is called, if setEngine(org.zkoss.zul.impl.ChartEngine) is not called with non-null engine.
    By default, it looks up the library property called org.zkoss.zul.chart.engine.class. If found, the value is assumed to be the class name of the chart engine (it must implement ChartEngine). If not found, UiException is thrown.
    Derived class might override this method to provide your own default class.
    
    Throws:
    
    org.zkoss.zk.ui.UiException - if failed to instantiate the engine
    
    Since:
    
    3.0.0
