chartjs-plugin-datalabels not showing values on chartjs

I am using the following versions:

Angular: 14.0.6
TypeScript: 4.7.4
chart.js: ^3.8.2
chartjs-plugin-annotation: ^1.4.0
chartjs-plugin-datalabels: ^2.0.0
ng2-charts: ^4.0.0

And I am trying to create a simple demo Doughnat Chart with dummy data. The problem is that the values are not shown on the chart, no matter what I tryied. I helped myself using that as an example but I figured out that with the newer version this approach is not working.. Here is what I tried so far..

My app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule } from '@angular/common/http';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HeaderComponent } from './header/header.component';
import { FoodManagementModule } from './food-management/food-management.module';
import { NgChartsModule } from 'ng2-charts';

@NgModule({
  declarations: [
    AppComponent,
    HeaderComponent,
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    HttpClientModule,
    FoodManagementModule,
    NgChartsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

My Template looks like that:

      <div class="container">
        <div class="row">
          <div class="col-sm-6">
            <canvas
              baseChart
              [datasets]="doughnutChartData"
              [labels]="doughnutChartLabels"
              [options]="doughnutChartOptions"
              [plugins]="doughnutChartPlugins"
              [legend]="doughnutChartLegend"
              [type]="doughnutChartType"
            >
            </canvas>
          </div>
        </div>
      </div>

In the TS file I've imported the pluginDataLabels as well as other types as follows:

import {
  ChartConfiguration,
  ChartDataset,
  ChartOptions,
  ChartType,
} from "chart.js";
import * as pluginDataLabels from "chartjs-plugin-datalabels";

and then I've tried like that:


 public doughnutChartOptions: ChartConfiguration<'doughnut'>['options'] = {
    responsive: true,
    plugins: {
      datalabels: {
        display: true,
        anchor: 'center',
        align: 'center',
        font: {
          size: 20,
        },
        color: "#000000"
      },
      tooltip: {
        enabled: true,
      },
      title: {
        display: true,
        text: 'Macros'
      },
      legend: {
        display: true,
      },
    },
  };

  // public doughnutChartOptions: ChartOptions = {
  //   responsive: true,
  //   plugins: {
  //     datalabels: {
  //       color: "#36A2EB",
  //       display: true,
  //       anchor: "end",
  //       align: "end",
  //       font: {
  //         size: 20,
  //       },
  //     },
  //   },

  public doughnutChartLabels: string[] = ["Proteins", "Carbohydrates", "Fats"];
  public doughnutChartType: ChartType = "doughnut";
  public doughnutChartLegend: boolean = true;
  public doughnutChartPlugins = [pluginDataLabels];
  public doughnutChartData: ChartDataset[] = [
    {
      label: "Example",
      data: [33, 44, 55],
      datalabels: {
        color: "#36A2EB",
        display: true,
      },
    },
  ];

  constructor() {}

  ngOnInit(): void { }

But nothing seems to work.. When I use the old versions and follow the example above, all works but I want to do it with the newer version.. Any suggestions what I am doing wrong?

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE".
