Basic Line Chart With Customizable line style

Following is an example of a basic line chart with a customized line style. 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 added lineWidth and line dash style configurations to change the default line style.

// Set chart options
var options = {
   series: {
      0: {
         lineWidth: 10,
         lineDashStyle: [5, 1, 5]
      },
      1: {
         lineWidth: 5,
         lineDashStyle: [7, 2, 4, 3]
      }
   }
};

Here 0 denotes the first series, 1 denotes the second series.
