Following is an example of a timelines 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 Timeline class to show the timelines diagram.

//Timeline chart
var chart = new google.visualization.Timeline(document.getElementById('container'));
