A Very Basic Chart
First, declare a chart component in a ZUML document. Assign type and title properties to it.
chart.zul
<charts id="chart" type="line" title="Season Average Temperature"
apply="org.zkoss.zkcharts.essentials.FirstChartComposer"/>
Use model to handle chart data, and set model to chart in a Controller which extends SelectorComposer
First≈ChartComposer.java
public class FirstChartComposer extends SelectorComposer<Component> {
@Wire
Charts chart;
public void doAfterCompose(Component comp) throws Exception {
super.doAfterCompose(comp);
// Create a predefined implementation category model
CategoryModel model = new DefaultCategoryModel();
// Set value to the model
model.setValue("Tokyo", "Spring", new Integer(11));
model.setValue("Tokyo", "Summer", new Integer(20));
model.setValue("Tokyo", "Fall", new Integer(16));
model.setValue("Tokyo", "Winter", new Integer(-2));
model.setValue("New York", "Spring", new Integer(6));
model.setValue("New York", "Summer", new Integer(12));
model.setValue("New York", "Fall", new Integer(10));
model.setValue("New York", "Winter", new Integer(2));
// Set model to the chart
chart.setModel(model);
}
}
After that, you can easily obtain an amazing chart to visualize your data.
Change Configuration
Moreover, if you want to change the configuration, you can add additional declarations in the composer:
// Get the legend option in chart
Legend legend = chart.getLegend();
// Chage lengend's layout to vertical
legend.setLayout("vertical");
// Change lengend's alignment
legend.setAlign("right");
legend.setVerticalAlign("middle");
// Remove lenged's border
legend.setBorderWidth(0);
The Legend of chart will be moved to the right of the chart without border.
