The best way to graphically represent data is to draw charts. ZK supports a few type of charts based on JFreeChart library. In this small talk, I will introduce a new component - ZHighCharts, based on Highcharts JS library which offers an easy way for users to create modern and intuitive charts.
Here are some selected demos:
More demos are available here: http://zhighcharts.appspot.com/demo.zul
To create a chart, four steps are required:
- Add zhighcharts-0.2.0.jar to the directory WEB-INF/lib
- Add the ZHighCharts component to the ZUL file
- Initialize and configure the component in the controller
- Add some data
<zhighcharts id="chartComp" />
ZHighCharts chartComp; chartComp = (ZHighCharts) getFellow("chartComp"); chartComp.setTitle("My first ZHighChart chart"); chartComp.setType("line");
SimpleExtXYModel dataChartModel = new SimpleExtXYModel(); chartComp.setModel(dataChartModel); dataChartModel.addValue("Chart 1", 0, 7); dataChartModel.addValue("Chart 1", 1, 4); dataChartModel.addValue("Chart 1", 2, 9); dataChartModel.addValue("Chart 1", 3, 5);
The ZHighCharts project is hosted on github here. To use ZHighCharts, a valid Highcharts license is required. Note that the use of Highcharts is free for non-profit organizations, students, universities, public schools and non-commercial personal websites. To use ZHighCharts for commercial services, a valid Highcharts license is required.
