2. 学习GWT_highcharts
3. Tree Map

Tree Map

以下是树图图表的示例。

我们已经在Highcharts Configuration Syntax一章中看到了用于绘制图表的配置 。

下面给出树形图的示例。

配置 (Configurations)

现在让我们看一下所采取的其他配置/步骤。

系列 (series)

将图表类型配置为“treemap”。 series.type决定图表的系列类型。 这里，默认值是“line”。

series.setType(Type.TREEMAP);

例子 (Example)

HelloWorld.java

package com.iowiki.client;
import org.moxieapps.gwt.highcharts.client.Chart;
import org.moxieapps.gwt.highcharts.client.Point;
import org.moxieapps.gwt.highcharts.client.Series;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;
public class HelloWorld implements EntryPoint {
   public void onModuleLoad() {
      final Chart chart = new Chart()
         .setChartTitleText("Fruit Consumption");  
      //Defining points to act as parents  
      final Point  appleParent = new Point("Apples")  
         .setColor("#EC2500");  
      final Point bananaParent = new Point("Bananas")  
         .setColor("#ECE100");  
      final Point orangeParent = new Point("Oranges")  
         .setColor("#EC9800");  
      chart.addSeries(chart.createSeries()  
         .setType(Series.Type.TREEMAP)
         .setPoints(new Point[]{  
            appleParent,  
            bananaParent,  
            orangeParent,  
            new Point("Anne", 5)  
               .setParent(appleParent),  
            new Point("Rick", 3)  
               .setParent(appleParent),  
            new Point("Peter", 4)  
               .setParent(appleParent),  
            new Point("Anne", 4)  
               .setParent(bananaParent),  
            new Point("Rick", 10)  
               .setParent(bananaParent),  
            new Point("Peter", 1)  
               .setParent(bananaParent),  
            new Point("Anne", 1)  
               .setParent(orangeParent),  
            new Point("Rick", 3)  
               .setParent(orangeParent),  
            new Point("Peter", 3)  
               .setParent(orangeParent),  
            new Point("Susanne", 2)  
               .setParent("Kiwi")  
               .setColor("#9EDE00")  
         })  
      );  
      RootPanel.get().add(chart);
   }
}
