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 Area Chart with missing values.

import { Component } from '@angular/core';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   title = 'Area Chart';
   type = 'AreaChart';
   data = [
      ["2013", 1000, 400],
      ["2014", 1170, 460],
      ["2015", null, 1120],
      ["2016", 1030, 540]
   ];
   columnNames = ['Year', 'Sales',"Expenses"];
   options = { };
   width = 550;
   height = 400;
}
