Pie Chart with exploded slices

Following is an example of a Pie Chart with exploded slices.

We have already seen the configurations used to draw a chart in Google Charts Configuration Syntax chapter. Now, let us see an example of a Pie Chart with exploded slices.

Configurations

We've used slices configuration to show a Pie Chart with exploded slices.

Slice slice1 = Slice.create();
slice1.setOffset(0.2);
Slice slice2 = Slice.create();

slice2.setOffset(0.3);
options.setSlice(1, slice1);
options.setSlice(3, slice2);

Example

HelloWorld.java

package com.tutorialspoint.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;

import com.googlecode.gwt.charts.client.ChartLoader;
import com.googlecode.gwt.charts.client.ChartPackage;
import com.googlecode.gwt.charts.client.ColumnType;
import com.googlecode.gwt.charts.client.DataTable;
import com.googlecode.gwt.charts.client.corechart.PieChart;
import com.googlecode.gwt.charts.client.corechart.PieChartOptions;
import com.googlecode.gwt.charts.client.options.Slice;

public class HelloWorld implements EntryPoint {
   private PieChart chart;

   private void initialize() {
      ChartLoader chartLoader = new ChartLoader(ChartPackage.CORECHART);
      chartLoader.loadApi(new Runnable() {
         public void run() {
            // Create and attach the chart
            chart = new PieChart();
            RootPanel.get().add(chart);
            draw();
         }
      });
   }
   private void draw() {
      // Prepare the data
      DataTable data = DataTable.create();
      data.addColumn(ColumnType.STRING, "Browser");
      data.addColumn(ColumnType.NUMBER, "Percentage");
      
      data.addRow("Firefox", 45.0);
      data.addRow("IE", 26.8);
      data.addRow("Chrome", 12.8);
      data.addRow("Safari", 8.5);
      data.addRow("Opera", 6.2);
      data.addRow("Others", 0.7);
      PieChartOptions options = PieChartOptions.create();

      options.setTitle("Browser market shares at a specific website, 2014");
      Slice slice1 = Slice.create();
      slice1.setOffset(0.2);
      Slice slice2 = Slice.create();
      
      slice2.setOffset(0.3);
      options.setSlice(1, slice1);
      options.setSlice(3, slice2);
      
      // Draw the chart
      chart.draw(data,options);
      chart.setWidth("400px");
      chart.setHeight("400px");
   }
   public void onModuleLoad() {
      initialize();
   }
}
