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.

  Sets the tick number font of y axis of this chart. If you saw squares rather than correct words in y axis tick, check whether the default y axis tick font supports your characters (e.g. Chinese). You probably have to set this font accordingly.
  
  Parameters:
  
  axisTickFont - the tick number font of y axis of this chart
- getYAxisFont
  
  public Font getYAxisFont()
  
  Returns the label font of y axis of this chart. If you saw squares rather than correct words in y axis label, check whether the default y axis label font supports your characters (e.g. Chinese). You probably have to set this font accordingly.
  
  Returns:
  
  the label font of y axis of this chart
- setYAxisFont
  
  public void setYAxisFont(Font axisFont)
  
  Sets the label font of y axis of this chart. If you saw squares rather than correct words in y axis label, check whether the default y axis label font supports your characters (e.g. Chinese). You probably have to set this font accordingly.
  
  Parameters:
  
  axisFont - the tick number font of y axis of this chart
- getEngine
  
  public ChartEngine getEngine() throws org.zkoss.zk.ui.UiException
  
  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
- setEngine
  
  public void setEngine(ChartEngine engine)
  
  Sets the chart engine.
- setEngine
  
  public void setEngine(String clsnm) throws ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InstantiationException, InvocationTargetException
  
  Sets the chart engine by use of a class name. It creates an instance automatically.
  
  Throws:
  
  ClassNotFoundException
  
  NoSuchMethodException
  
  IllegalAccessException
  
  InstantiationException
  
  InvocationTargetException
- getAreaListener
  
  public ChartAreaListener getAreaListener()
  
  Returns the renderer to render each area, or null if the default renderer is used.
- setAreaListener
  
  public void setAreaListener(ChartAreaListener listener)
  
  Sets the renderer which is used to render each area.
  Note: changing a render will not cause the chart to re-render. If you want it to re-render, you could call smartDraw.
  
  Parameters:
  
  listener - the area listener, or null to ignore it.
  
  Throws:
  
  org.zkoss.zk.ui.UiException - if failed to initialize.
- setAreaListener
  
  public void setAreaListener(String clsnm) throws ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InstantiationException, InvocationTargetException
  
  Sets the renderer by use of a class name. It creates an instance automatically.
  
  Throws:

- addEventListener
  
  public boolean addEventListener(String evtnm, org.zkoss.zk.ui.event.EventListener<? extends org.zkoss.zk.ui.event.Event> listener)
  
  Specified by:
  
  addEventListener in interface org.zkoss.zk.ui.Component
  
  Overrides:
