        Sets the legend font of this chart. If you saw squares rather than correct words in legend, check whether the default legend font supports your characters (e.g. Chinese). You probably have to set this font accordingly.
        Parameters:
        font - the legend font 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

      • getAreaListener

        public ChartAreaListener getAreaListener()
        Returns the renderer to render each area, or null if the default renderer is used.
      • setAreaListener

        listener - the area listener, or null to ignore it.
        Throws:
        org.zkoss.zk.ui.UiException - if failed to initialize.
