Manipulating Chart Model


Manipulating Model

Models are the perfect way for developers to interact with the charts as they shield developers from complexities that they need not know or interact with. In addition to this ZK model supports many design patterns including MVC[1] and MVVM[2], which are both fully supported patterns.

ZK provides chart model [3] to handle data in the chart. Manipulating chart model with charts is the same as other ZK components handling their supporting models. We've used MVC approach to create the chart in previous section - Create your first ZK Charts. In this section, we will create another example to manipulate chart model in MVVM approach.

We get started from creating an XYModel and put the data we want to handle:

ChartData.java

public class ChartData {

    static public XYModel getXYModel() {
        // Use the predefined implementation SimpleXYModel to create an model.
        XYModel model = new SimpleXYModel();

        model.addValue("2001", new Integer(20), new Integer(120));
        model.addValue("2001", new Integer(40), new Integer(135));
        model.addValue("2001", new Integer(60), new Integer(140));
        model.addValue("2001", new Integer(80), new Integer(160));
		 
        model.addValue("2002", new Integer(30), new Integer(120));
        model.addValue("2002", new Integer(50), new Integer(135));
        model.addValue("2002", new Integer(70), new Integer(140));
        model.addValue("2002", new Integer(90), new Integer(160));

        return model;
    }
}

Declare a POJO VM as well as the property's getter method.

ChartVM.java

public class ChartVM {

    public XYModel getModel() {
        return ChartData.getXYModel();
    }
}

Reference the ViewModel in ZUL:

chart.zul

<window apply="org.zkoss.bind.BindComposer" viewModel="@id('vm') @init('ChartVM')">
    <charts type="bar" model="@bind(vm.model)" />
</window>
