Following is an example of a material line chart. 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 Line class to show the material chart.
//classic chart
var chart = new google.visualization.LineChart(document.getElementById('container'));
//Material chart
var chart = new google.charts.Line(document.getElementById('container'));
