Histogram Chart with multiple series
Following is an example of a Histogram Chart with multiple series.
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 histogram chart with multiple series.
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.DataTable; import com.googlecode.gwt.charts.client.corechart.Histogram; import com.googlecode.gwt.charts.client.corechart.HistogramOptions; import com.googlecode.gwt.charts.client.options.Legend; import com.googlecode.gwt.charts.client.options.LegendPosition; import com.googlecode.gwt.charts.client.util.ChartHelper; public class HelloWorld implements EntryPoint { private Histogram chart; private void initialize() { ChartLoader chartLoader = new ChartLoader(ChartPackage.CORECHART); chartLoader.loadApi(new Runnable() { public void run() { // Create and attach the chart chart = new Histogram(); RootPanel.get().add(chart); draw(); } }); } private void draw() { // Prepare the data Object[][] data = new Object[][] { { "Student Roll No", "Height", "Weight" }, {"1", 80, 40},{"2", 55, 30},{"3", 68, 34},{"4", 80, 40},{"5", 54, 27}, {"6", 70, 35},{"7", 85, 42},{"8", 78, 40},{"9", 70, 35},{"10", 58, 28}, {"11", 90, 45},{"12", 65, 33},{"13", 88, 50},{"14", 82, 41},{"15", 65, 30}, {"16", 86, 43},{"17", 45, 30},{"18", 62, 30},{"19", 84, 42},{"20", 75, 40}, {"21", 82, 41},{"22", 75, 40},{"23", 58, 30},{"24", 70, 35},{"25", 85, 40} }; DataTable dataTable = ChartHelper.arrayToDataTable(data); // Set options HistogramOptions options = HistogramOptions.create(); options.setTitle("Students height, in cm"); options.setLegend(Legend.create(LegendPosition.NONE)); options.setBucketSize(5); // Draw the chart chart.draw(dataTable,options); chart.setWidth("400px"); chart.setHeight("400px"); } public void onModuleLoad() { initialize(); } }
