Area Chart with missing values

Following is an example of an area chart with missing values.

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 with missing values. We have added spacingBottom attribute in chart.

charts

Configure the spacingBottom of the chart as 30. It signifies the space between the bottom edge of the chart and the content (plot area, axis title and labels, title, subtitle or legend in top position).

var chart = {
   type: 'area',
   spacingBottom: 30
};

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: 'area',
         spacingBottom: 30
      },
      title: {
         text: 'Fruit consumption *'
      },
      subtitle : {
         text: '* Jane\'s banana consumption is unknown',
         floating: true,
         align: 'right',
         verticalAlign: 'bottom',
         y: 15
      },
      legend : {
         layout: 'vertical',
         align: 'left',
         verticalAlign: 'top',
         x: 150,
         y: 100,
         floating: true,
         borderWidth: 1,
         backgroundColor: (
            Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'
      },
      xAxis:{
         categories: ['Apples', 'Pears', 'Oranges', 'Bananas', 'Grapes', 'Plums', 'Strawberries', 'Raspberries']
      },
      yAxis : {
         title: {
            text: 'Y-Axis'
         },
         labels: {
            formatter: function () {
               return this.value;
            }
         }
      },
      tooltip : {
         formatter: function () {
            return '<b>' + this.series.name + '</b><br/>' +
               this.x + ': ' + this.y;
         }
      },
      plotOptions : {
         area: {
            fillOpacity: 0.5 
         }
      },
      credits:{
         enabled: false
      },
      series: [
         {
            name: 'John',
            data: [0, 1, 4, 4, 5, 2, 3, 7]
         }, 
         {
            name: 'Jane',
            data: [1, 0, 3, null, 3, 1, 2, 1]
         }
      ]
   };
