Column Chart with data labels

Following is an example of a column chart with data labels. We’ve already seen the configuration used to draw this chart in the Google Charts Configuration Syntax chapter. So, let’s see the complete example.

Configurations

We’ve used the role of annotation configuration to show data labels in column charts.

var data = google.visualization.arrayToDataTable([
   ['Year', 'Asia', { role: 'annotation'} ,'Europe', { role: 'annotation'}],
   ['2012',  900,'900',      390, '390']
]);

            var options = {title: 'Population (in millions)'};  
 
            // Instantiate and draw the chart.
            var chart = new google.visualization.ColumnChart(document.getElementById('container'));
            chart.draw(data, options);
         }
