title: Type 'number[]' has no properties in common with type 'XrangePointOptionsObject' in Angular8 using Highcharts
body: <p>I am trying to add a Heatmap using highcharts in Angular8 however the typescript shows the following error </p>
  
  <blockquote>
    <p>"Type 'number[]' has no properties in common with type
    'XrangePointOptionsObject'."</p>
  </blockquote>
  
  <p>So i know that the error comes from the part series.data, when i comment out the data arrays the page loads with empty fields on the heatmap. I have developed similar charts using javascript before but this is the first time i am using typescript to create a chart. The Highchart options for this heatmap are basically from here - <a href="https://www.tutorialspoint.com/angular_highcharts/angular_highcharts_heat_map.htm" rel="noreferrer">https://www.tutorialspoint.com/angular_highcharts/angular_highcharts_heat_map.htm</a></p>
  
  <p>This is the .ts file for the heatmap :</p>
  
  <pre><code>import { Component, OnInit } from '@angular/core';
  import * as Highcharts from 'highcharts';
  import * as highchartsHeatmap from 'highcharts/modules/heatmap';
  import HeatmapModule from 'highcharts/modules/heatmap';
  HeatmapModule(Highcharts);
  
  @Component({
    selector: 'app-heatmap',
    template: '&lt;div id="container"style="height: 400px; min-width: 380px"&gt;&lt;/div&gt;',
  })
  
  export class HeatMapComponent implements OnInit {
  
    chartObject: Highcharts.Chart = null;
    constructor() {
  
    }
  
    ngOnInit() {
      this.chartObject = Highcharts.chart(
  
        {
          chart: {
            renderTo:"container",
            type: 'heatmap',

  <p>What is the correct way to insert chart options using typescript for creating a chart and avoiding similar errors?
  Best regards!</p>
