GWT Google Charts - Table Chart


Advertisements

Table chart helps in rendering a table which can be sorted and paged. Table cells can be formatted using format strings, or by directly inserting HTML as cell values. Numeric values are right-aligned by default; boolean values are displayed as check marks or cross marks. Users can select single rows either with the keyboard or the mouse. Column headers can be used for sorting. The header row remains fixed during scrolling. The table fires events corresponding to user interaction.

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 Table Chart.

Configurations

We've used Table class to show a Table chart.

Table chart = new Chart();

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.table.Table;
import com.googlecode.gwt.charts.client.table.TableOptions;

public class HelloWorld implements EntryPoint {
   private Table chart;

   private void initialize() {
      ChartLoader chartLoader = new ChartLoader(ChartPackage.TABLE);
      chartLoader.loadApi(new Runnable() {
         public void run() {
            // Create and attach the chart
            chart = new Table();
            RootPanel.get().add(chart);
            draw();
         }
      });
   }
   private void draw() {
      // Prepare the data
      DataTable dataTable = DataTable.create();
      dataTable.addColumn(ColumnType.STRING, "Name");
      dataTable.addColumn(ColumnType.NUMBER, "Salary");
      dataTable.addColumn(ColumnType.BOOLEAN, "Full Time Employee");
      dataTable.addRows(4);
      
      dataTable.setCell(0, 0, "Mike");
      dataTable.setCell(0, 1, 10000, "$10,000");
      dataTable.setCell(0, 2, true);
      dataTable.setCell(1, 0, "Jim");
      dataTable.setCell(1, 1, 8000, "$8,000");
      dataTable.setCell(1, 2, false);
      dataTable.setCell(2, 0, "Alice");
      dataTable.setCell(2, 1, 12500, "$12,500");
      dataTable.setCell(2, 2, true);
      dataTable.setCell(3, 0, "Bob");
      dataTable.setCell(3, 1, 7000, "$7,000");
      dataTable.setCell(3, 2, true);

      TableOptions options  = TableOptions.create();
      options.setAlternatingRowStyle(true);
      options.setShowRowNumber(true);
      
      // Draw the chart
      chart.draw(dataTable, options);
      chart.setWidth("400px");
      chart.setHeight("400px");
   }
   public void onModuleLoad() {
      initialize();
   }
}
