GWT Highcharts - 树形图

以下是一个树形图示例。

我们在 Highcharts 配置语法 章节中已经看到了用于绘制图表的配置。

下面提供了一个树形图示例。

配置

现在让我们查看附加的配置/步骤。

series

将图表类型配置为以“treemap”为基础。series.type 决定了图表系列类型。此处，默认值为“line”。

series.setType(Type.TREEMAP);

示例

HelloWorld.java

package com.tutorialspoint.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);
   }
}

结果
