Hello friends In this article, we will learn how to implement apexcharts bar chart in Angular 12.. Charts are very useful for showing data and people understand the data very easily. So we will use apexcharts for creating a Column chart in Angular-12.

What is ApexCharts?

  • ApexCharts may be a modern charting library that creates stunning and interactive visualizations for websites.
  • It is open-source and is free to use in commercial applications.

Let us understand it with an example.

First, create a new project in Angular using this command.

ng new AngularColumnChart

Then open the project in visual code and install the following package.

npm install apexcharts ng-apexcharts --save

Now open app.module.ts and add the following code.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { NgApexchartsModule } from 'ng-apexcharts';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [BrowserModule, NgApexchartsModule],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Now open app.component.ts and add the following code.

import { Component, ViewChild } from '@angular/core';
import {
  ApexChart,
  ApexAxisChartSeries,
  ChartComponent,
  ApexDataLabels,
  ApexPlotOptions,
  ApexYAxis,
  ApexLegend,
  ApexGrid
} from "ng-apexcharts";

type ApexXAxis = {
  type?: "category" | "datetime" | "numeric";
  categories?: any;
  labels?: {
    style?: {
      colors?: string | string[];
      fontSize?: string;
    };
  };
};

export type ChartOptions = {
  series: ApexAxisChartSeries;
  chart: ApexChart;
  dataLabels: ApexDataLabels;
  plotOptions: ApexPlotOptions;
  yaxis: ApexYAxis;
  xaxis: ApexXAxis;
  grid: ApexGrid;
  colors: string[];
  legend: ApexLegend;
};

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  @ViewChild("chart") chart: ChartComponent | any;
  public chartOptions: Partial<ChartOptions> | any;

  constructor() {
    this.chartOptions = {
      series: [
        {
          name: "Marks",
          data: [21, 22, 10, 28, 16, 21, 13, 30]
        }
      ],
      chart: {
        height: 350,
        width: 1000,
        type: "bar"
      },
      plotOptions: {
        bar: {
          columnWidth: "45%",
          distributed: true
        }
      },
      dataLabels: {
        enabled: true
      },
      legend: {
        show: true
      },
      grid: {
        show: true
      },
      xaxis: {
        categories: [
          ["parth"],
          ["Sagar"],
          ["Dipak"],
          ["Yasin"],
          ["Utsav"],
          ["Ravi"],
          ["Krushit"],
          ["Priyank"]
        ],
        labels: {
          style: {
            colors: [
              "#008FFB",
              "#00E396",
              "#FEB019",
              "#FF4560",
              "#775DD0",
              "#546E7A",
              "#26a69a",
              "#D10CE8"
            ],
            fontSize: "12px"
          }
        }
      }
    };
  }
}

Finally, add the code in the app.component.html file and that’s it.

<apx-chart [series]="chartOptions.series" [chart]="chartOptions.chart" [dataLabels]="chartOptions.dataLabels"
  [plotOptions]="chartOptions.plotOptions" [yaxis]="chartOptions.yaxis" [xaxis]="chartOptions.xaxis"
  [legend]="chartOptions.legend" [colors]="chartOptions.colors" [grid]="chartOptions.grid"></apx-chart>
