GWT Google Charts - Basic Stepped Chart
Following is an example of a Stepped Chart.
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 Stepped Chart.
Configurations
We've used ScatterChart class to show a Stepped chart.
SteppedChart chart = new SteppedChart();
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.SteppedAreaChart; import com.googlecode.gwt.charts.client.corechart.SteppedAreaChartOptions; import com.googlecode.gwt.charts.client.options.VAxis; public class HelloWorld implements EntryPoint { private SteppedAreaChart chart; private void initialize() { ChartLoader chartLoader = new ChartLoader(ChartPackage.CORECHART); chartLoader.loadApi(new Runnable() { public void run() { // Create and attach the chart chart = new SteppedAreaChart(); RootPanel.get().add(chart); draw(); } }); } private void draw() { // Prepare the data DataTable data = DataTable.create(); data.addColumn(ColumnType.STRING, "Director (Year)"); data.addColumn(ColumnType.NUMBER, "Rotten Tomatoes"); data.addColumn(ColumnType.NUMBER, "IMDB"); data.addRow("Alfred Hitchcock (1935)", 8.4, 7.9); data.addRow("Ralph Thomas (1959)", 6.9, 6.5); data.addRow("Don Sharp (1978)", 6.5, 6.4); data.addRow("James Hawes (2008)", 4.4, 6.2); SteppedAreaChartOptions options = SteppedAreaChartOptions.create(); options.setTitle("The decline of 'The 39 Steps'"); VAxis vAxis = VAxis.create(); vAxis.setTitle("Accumulated Rating"); // Draw the chart chart.draw(data, options); chart.setWidth("400px"); chart.setHeight("400px"); } public void onModuleLoad() { initialize(); } }
