Employment/Purpose

A chart is used to show a set of data as a graph. It helps users to judge things with a snapshot. To use a chart component , developers must prepare a ChartModel and a ChartEngine. Developers also set proper chart type, and the threeD (3D) attribute to draw a proper chart. The model and type must match each other, or the result is unpredictable. The 3D chart is not supported on all chart types.

Example

Pie Chart

    ]]></attribute>
    <zscript><![CDATA[
        PieModel model = new SimplePieModel();
        model.setValue("C/C++", new Double(21.2));

Clicked Area: Series, Legend

In an onClick listener, you can call MouseEvent.getX() and MouseEvent.getY() to get coordinates.

Call MouseEvent.getAreaComponent() to retrieve the area component (Area) which users click on.

There are several attributes you can get from the clicked Area:

series: series name
category: category name, e.g. GanttTask's description
entity: could be DATA or LEGEND
percent: percentage of complete of a gantt task
start: start value of a gannt task
end: end value of a gannt task

	
    @Listen("onClick = #gantt")
    public  void drilldown(MouseEvent event) {
        final Area area = (Area)event.getAreaComponent();
        if (area != null)
            Messagebox.show(area.getAttribute("category")+": "+area.getTooltiptext());
    }

Charts Support Setting the Font

We can now specify what font we want a chart to use. This is useful when employing a foreign language within your chart. The example demonstrates setting a font and using it with a foreign language, in this case Chinese.

	<zscript>
		import java.awt.Font;
		String fontname = "Dialog";
		Font tfont = new Font(fontname, Font.BOLD, 16); //for title
		Font lfont = new Font(fontname, Font.PLAIN, 10); //for legend
		Font lbfont = new Font(fontname, Font.PLAIN, 12); //for label


		CategoryModel catmodel = new SimpleCategoryModel();
		catmodel.setValue("2001", "第一季", new Integer(20));
		catmodel.setValue("2001", "第二季", new Integer(35));
		catmodel.setValue("2001", "第三季", new Integer(40));
		catmodel.setValue("2001", "第四季", new Integer(55));
		catmodel.setValue("2002", "第一季", new Integer(40));
		catmodel.setValue("2002", "第二季", new Integer(60));
		catmodel.setValue("2002", "第三季", new Integer(70));
		catmodel.setValue("2002", "第四季", new Integer(90));
	</zscript>

Customize Chart

You can customize a chart's appearance by providing your own ChartEngine. It can save your effort by extending JFreeChartEngine and override its prepareJFreeChart(). Then manipulate the passed JFreeChart to change a chart's rendering. You also need to find related API in JFreeChart JavaDoc.

<chart engine="foo.MyJfreeChartEngine"/>

Linux

Chart depends on Java Swing that might not work under some version of JVM. For the information to make it work under Linux, please refer to ZK Installation Guide: Linux.

Version History

Last Update : 2023/03/01

Version	Date	Content
5.0.4	August 2010	MouseEvent introduced a new method, MouseEvent.getAreaComponent(), which simplifies the retrieval of the area component. Area area = (Area)event.getAreaComponent(); //must be Area or null when used with chart if (area != null) ...
5.0.3	June 2010	The area sent with the click event becomes UUID of the area component. Thus, use `desktop.getComponentByUuid(event.getArea())`. To write a program compatible with any version of ZK: String areaid = event.getArea(); if (areaid != null) { Area area = desktop.getComponentByUuidIfAny(areaid); if (area == null) area = chart.getFellow(areaid); //fall back to older version ...
