GWT Highcharts - Basic Line Chart


Advertisements

We have already seen the configuration used to draw this chart in Highcharts Configuration Syntax chapter. Let us now consider the following example to further understand a basic line chart.

Example

HelloWorld.java

package com.tutorialspoint.client;

import org.moxieapps.gwt.highcharts.client.Chart;
import org.moxieapps.gwt.highcharts.client.Legend;
import org.moxieapps.gwt.highcharts.client.Series.Type;
import org.moxieapps.gwt.highcharts.client.ToolTip;
import org.moxieapps.gwt.highcharts.client.XAxis;
import org.moxieapps.gwt.highcharts.client.YAxis;

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

public class HelloWorld implements EntryPoint {
   public void onModuleLoad() {
      Chart chart = new Chart()
         .setType(Type.SPLINE)
         .setChartTitleText("Monthly Average Temperature")
         .setChartSubtitleText("Source: WorldClimate.com");

      XAxis xAxis = chart.getXAxis();
      xAxis.setCategories("Jan", "Feb", "Mar", "Apr", "May", "Jun",
         "Jul", "Aug", "Sep", "Oct", "Nov", "Dec");

      YAxis yAxis = chart.getYAxis();
      yAxis.setAxisTitleText("Temperature °C");
      yAxis.createPlotLine()
         .setValue(0)
         .setWidth(1)
         .setColor("#808080");

      ToolTip toolTip = new ToolTip();
      toolTip.setValueSuffix("°C");
      chart.setToolTip(toolTip);

      Legend legend = new Legend();
      legend.setLayout(Legend.Layout.VERTICAL)
         .setAlign(Legend.Align.RIGHT)
         .setVerticalAlign(Legend.VerticalAlign.TOP)
         .setX(-10)
         .setY(100)
         .setBorderWidth(0);
      chart.setLegend(legend);

      chart.addSeries(chart.createSeries()
         .setName("Tokyo")
         .setPoints(new Number[] {
            7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,
            26.5, 23.3, 18.3, 13.9, 9.6
         })
      );

      chart.addSeries(chart.createSeries()
         .setName("New York")
         .setPoints(new Number[] {
            -0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 
            24.1, 20.1, 14.1, 8.6, 2.5
         })
      );

      chart.addSeries(chart.createSeries()
         .setName("Berlin")
         .setPoints(new Number[] {
            -0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6,
            17.9, 14.3, 9.0, 3.9, 1.0
         })
      );

      chart.addSeries(chart.createSeries()
         .setName("London")
         .setPoints(new Number[] {
            3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 
            16.6, 14.2, 10.3, 6.6, 4.8
         })
      );
      RootPanel.get().add(chart);
   }
}
