How to use chart.js in angular

I'm trying implement chart.js in my angular project. There're not any error when compiling but the chart isn't showed. I don't know why.

This is chartjs.component.html

<canvas id="canvas">{{chart}}</canvas>


This is chartjs.component.ts

import { Component, OnInit } from '@angular/core';
import { Chart } from "chart.js";

@Component({
selector: 'app-chartjs',
templateUrl: './chartjs.component.html',
styleUrls: ['./chartjs.component.scss']
})
export class ChartjsComponent implements OnInit {
public chart: any = null;

ngOnInit() {
this.chart = new Chart("canvas", {
type: 'bar',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
}
});





}

}


And i'm calling it in a selector called <app-chartjs></app-chartjs> in dashboard.component.html

I also added "node_modules/chart.js/dist/Chart.js" in the section script of angular.json.

Any soluction please...
