How To Implement HighCharts In Angular 13

In this article, we are going to learn about highcharts. In order to add highcharts, we will use the step by step process, which is described as follows:

Step 1 :

At first, we are going create new app. the following command will be used

ng new HighchartsExample

Step 2 :

In this step, we are going to Install Npm Package using command

npm install highcharts –save

npm install highcharts-angular –save

Step 3 :

In app.component.ts

import { AfterViewInit, Component} from '@angular/core';
import * as Highcharts from 'highcharts';
import HighchartsMore from 'highcharts/highcharts-more';
import HighchartsSolidGauge from 'highcharts/modules/solid-gauge';

HighchartsMore(Highcharts);
HighchartsSolidGauge(Highcharts);

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponentimplements AfterViewInit {
  public ngAfterViewInit(): void {
    this.GaugeChart();
    this.PieChart();
    this.ColumnChart();
    this.LineChart();
  }

  private getRandomNumber(min: number, max: number): number {
    return Math.floor(Math.random() * (max - min + 1) + min)
  }

  private GaugeChart(): void {
    const chart = Highcharts.chart('chart-gauge', {
      chart: {
        type: 'solidgauge',
      },
      title: {
        text: 'Gauge Chart',
      },
      credits: {
        enabled: false,
      },
      pane: {
        startAngle: -90,
        endAngle: 90,
        center: ['50%', '85%'],
        size: '160%',
        background: {
            innerRadius: '60%',
            outerRadius: '100%',
            shape: 'arc',
        },
      },
      yAxis: {
        min: 0,
        max: 100,
        stops: [
          [0.1, '#55BF3B'], // green
          [0.5, '#DDDF0D'], // yellow

            borderWidth: 0,
            useHTML: true,
          },
        },
      },
      tooltip: {
        enabled: false,
      },
      series: [{
        name: null,
        data: [this.getRandomNumber(0, 100)],
        dataLabels: {
          format: '<div style="text-align: center"><span style="font-size: 1.25rem">{y}</span></div>',
        },
      }],
    } as any);

    setInterval(() => {
      chart.series[0].points[0].update(this.getRandomNumber(0, 100));
    }, 1000);
  }

  private PieChart(): void {
    let date = new Date();
    const data: any[] = [];

    for (let i = 0; i < 5; i++) {
      date.setDate(new Date().getDate() + i);
      data.push({
        name: `${date.getDate()}/${date.getMonth() + 1}`,
        y: this.getRandomNumber(0, 1000),
      });
    }

    const chart = Highcharts.chart('chart-pie', {
      chart: {
        type: 'pie',
      },
      title: {
        text: 'Pie Chart',
      },
      credits: {

    } as any);

    setInterval(() => {
      date.setDate(date.getDate() + 1);
      chart.series[0].addPoint({
        name: `${date.getDate()}/${date.getMonth() + 1}`,
        y: this.getRandomNumber(0, 1000),
      }, true, true);
    }, 1500);
  }

  private ColumnChart(): void {
    let date = new Date();
    const data: any[] = [];

    for (let i = 0; i < 10; i++) {
      date.setDate(new Date().getDate() + i);
      data.push({
        name: `${date.getDate()}/${date.getMonth() + 1}`,
        y: this.getRandomNumber(0, 1000),
      });
    }

    const chart = Highcharts.chart('chart-column' as any, {
      chart: {
        type: 'column',
      },
      title: {
        text: 'Column Chart',
      },
      credits: {

      legend: {

      },
      yAxis: {
        min: 0,
        title: undefined,
      },
      xAxis: {
        type: 'category',
      },
      tooltip: {
        headerFormat: `<div>Date: {point.key}</div>`,
        pointFormat: `<div>{series.name}: {point.y}</div>`,
        shared: true,
        useHTML: true,
      },
      plotOptions: {
        bar: {
          dataLabels: {

          },
        },
      },
      series: [{
        name: 'Amount',
        data,
      }],
    } as any);

    setInterval(() => {
      date.setDate(date.getDate() + 1);
      chart.series[0].addPoint({
        name: `${date.getDate()}/${date.getMonth() + 1}`,
        y: this.getRandomNumber(0, 1000),
      }, true, true);
    }, 1500);
  }

  private LineChart(): void {
    let date = new Date();
    const data: any[] = [];

    for (let i = 0; i < 10; i++) {
      date.setDate(new Date().getDate() + i);
      data.push([`${date.getDate()}/${date.getMonth() + 1}`, this.getRandomNumber(0, 1000)]);
    }

    const chart = Highcharts.chart('chart-line', {
      chart: {
        type: 'line',
      },
      title: {
        text: 'Line Chart',
      },
      credits: {
        enabled: false,
      },
      legend: {
        enabled: false,
      },
      yAxis: {
        title: {
          text: null,
        }
      },
      xAxis: {
        type: 'category',
      },
      tooltip: {
        headerFormat: `<div>Date: {point.key}</div>`,
        pointFormat: `<div>{series.name}: {point.y}</div>`,

        useHTML: true,
      },
      series: [{
        name: 'Amount',
        data,
      }],
    } as any);

    setInterval(() => {
      date.setDate(date.getDate() + 1);
      chart.series[0].addPoint([`${date.getDate()}/${date.getMonth() + 1}`, this.getRandomNumber(0, 1000)], true, true);
    }, 1500);
  }
}

Step 4 :

In app.component.html

<main id="main">
  <div id="chart-gauge"></div>
  <div id="chart-pie"></div>
  <div id="chart-line"></div>
  <div id="chart-column"></div>
</main>

Step 5 :

In app.component.scss

#main{
  display: flex;
}

#chart-gauge, #chart-pie, #chart-column, #chart-line {
  display: block;
  min-width: 300px;
  max-width: 400px;
  height: 200px;
  margin: 0 auto;
}

Step 6 :

Now our above code is ready to run. we will use the following command:

ng serve
