Type'number []'与使用Highcharts的Angular8中的'XrangePointOptionsObject'类型没有共同的属性

问题描述 投票:0回答:1

[我正在尝试使用Angular8中的highcharts添加热图,但是打字稿显示以下错误

“ Type'number []'没有与type相同的属性'XrangePointOptionsObject'。“

因此,我知道错误来自于series.data部分,当我注释掉数据数组时,页面会在热图上显示空白字段。我以前使用javascript开发过类似的图表,但这是我第一次使用打字稿来创建图表。此热图的Highchart选项基本上来自此处-https://www.tutorialspoint.com/angular_highcharts/angular_highcharts_heat_map.htm

这是热图的.ts文件:

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'
          }
        }]

      }



    );
  }

}

使用打字稿创建图表并避免类似错误的插入图表选项的正确方法是什么?最好的问候!

所以我设法自己解决了这个错误。如果有人遇到相同的错误,请使用以下代码:

import { Component, OnInit } from '@angular/core';
import * as Highcharts from 'highcharts';
import HeatmapModule from 'highcharts/modules/heatmap';
HeatmapModule(Highcharts);

@Component({
  selector: 'app-heatmap',
  template: '<div id="heatmap-object"style="height: 400px; min-width: 380px"></div>',
})

export class HeatMapComponent implements OnInit {


  HeatmapObject: Highcharts.Chart = null;
  constructor() { }

  ngOnInit() {
    let options = this.HeatmapOptions();
    this.HeatmapObject = Highcharts.chart(options);
  }

  HeatmapOptions(): Highcharts.Options {

    let options: Highcharts.Options = {

      chart: {
        renderTo: 'heatmap-object',
        marginTop: 40,
        marginBottom: 80,
        plotBorderWidth: 1
      },
      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: [{
        type: 'heatmap',
        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'
        }
      }]

    }

    return options;
  }
