Type 'number[]' has no properties in common with type 'XrangePointOptionsObject' in Angular8 using Highcharts

Question

I am trying to add a Heatmap using highcharts in Angular8 however the typescript shows the following error

"Type 'number[]' has no properties in common with type 'XrangePointOptionsObject'."

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 - https://www.tutorialspoint.com/angular_highcharts/angular_highcharts_heat_map.htm

This is the .ts file for the heatmap :

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: '<div id="container"style="height: 400px; min-width: 380px"></div>',
})

export class HeatMapComponent implements OnInit {

  chartObject: Highcharts.Chart = null;
  constructor() {

  }

  ngOnInit() {
    this.chartObject = Highcharts.chart(

      {
        chart: {
          renderTo:"container",
          type: 'heatmap',
          marginTop: 40,
          marginBottom: 80
        },
        title: {
          text: 'Sales per employee per weekday'
        },
        xAxis: {
          categories: ['Alexander', 'Marie', 'Maximilian', 'Sophia', 'Lukas',
            'Maria', 'Leon', 'Anna', 'Tim', 'Laura']
        },
        yAxis: {
          categories: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'],
          title: null
        },
        colorAxis: {
          min: 0,
          minColor: '#FFFFFF',
          maxColor: Highcharts.getOptions().colors[0]
        },
        legend: {
          align: 'right',
          layout: 'vertical',
          margin: 0,
          verticalAlign: 'top',
          y: 25,
          symbolHeight: 280
        },
        tooltip: {
          formatter: function () {
            return '<b>' + this.series.xAxis.categories[this.point.x] +
              '</b> sold <br><b>' +
              this.point.value +
              '</b> items on <br><b>' +
              this.series.yAxis.categories[this.point.y] + '</b>';
          }
        },
        series: [{
          name: 'sales per employee',
          borderwidth: 1,
          data: [[0, 0, 10], [0, 1, 19], [0, 2, 8], [0, 3, 24], [0, 4, 67],
          [1, 0, 92], [1, 1, 58], [1, 2, 78], [1, 3, 117], [1, 4, 48],
          [2, 0, 35], [2, 1, 15], [2, 2, 123], [2, 3, 64], [2, 4, 52],
          [3, 0, 72], [3, 1, 132], [3, 2, 114], [3, 3, 19], [3, 4, 16],
          [4, 0, 38], [4, 1, 5], [4, 2, 8], [4, 3, 117], [4, 4, 115],
          [5, 0, 88], [5, 1, 32], [5, 2, 12], [5, 3, 6], [5, 4, 120],
          [6, 0, 13], [6, 1, 44], [6, 2, 88], [6, 3, 98], [6, 4, 96],
          [7, 0, 31], [7, 1, 1], [7, 2, 82], [7, 3, 32], [7, 4, 30],
          [8, 0, 85], [8, 1, 97], [8, 2, 123], [8, 3, 64], [8, 4, 84],
          [9, 0, 47], [9, 1, 114], [9, 2, 31], [9, 3, 48], [9, 4, 91]],

          datalabels: {
            enabled: true,
            color: '#000000'
          }
        }]

      }



    );
  }

}

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

Answer 1

You need to Define the type per series.

https://api.highcharts.com/highcharts/series.line

Answer 2

in the attribute "series", you need to add the type like this :

series: [
        {type: undefined,
        name: 'name I',
        data:[1,2,3]},
       {type: undefined,
        name: 'name II',
        data:[4,5,6]}],
