Area Chart using Spline

We have already seen the configurations used to draw a chart in Highcharts Configuration Syntax chapter. Now, let us see an example of a Area Chart using spline. We will also understand additional configuration. We have changed the type attribute in chart.

chart

Configure the chart type to be 'areaspline' based. chart.type decides the series type for the chart. Here, the default value is "line".

var chart = {
   type: 'areaspline'  
};

Example

app.component.ts

import { Component } from '@angular/core';
import * as Highcharts from 'highcharts';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   highcharts = Highcharts;
   chartOptions = {   
      chart: {
        type: 'areaspline'
      },
      title: {
        text: 'Average fruit consumption during one week'
      },
      subtitle : {
         style: {
            position: 'absolute',
            right: '0px',
            bottom: '10px'
         }
      },
      legend : {
         layout: 'vertical',
         align: 'left',
         verticalAlign: 'top',
         x: -150,
         y: 100,
         floating: true,
         borderWidth: 1,
        
         backgroundColor: (
            Highcharts.theme && Highcharts.theme.legendBackgroundColor) || 
              '#FFFFFF'
      },
      xAxis:{
         categories: ['Monday','Tuesday','Wednesday','Thursday',
            'Friday','Saturday','Sunday'] 
      },
      yAxis : {
         title: {
            text: 'Number of units'
         }
      },
      tooltip : {
         shared: true, valueSuffix: ' units'
      },
      plotOptions : {
         area: {
            fillOpacity: 0.5 
         }
      },
      credits:{
        enabled: false
      },
      series: [
         {
            name: 'John',
            data: [3, 4, 3, 5, 4, 10, 12]
         }, 
         {
            name: 'Jane',
            data: [1, 3, 4, 3, 3, 5, 4]
         }
      ]
   };
}
