Chart

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

Example

Pie Chart

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.

ZKComRef Chart Font Examples.png

	<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));

Troubleshooting

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 : 2018/7/20


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
...
