However at the time does not display the graph. I tested in simple html and it worked. But at angular no..

How did you add the Canvasjs library to your project? Did you add it in angular-cli.json? gives a look here: https://github.com/angular-cli/wiki/stories-global-scripts

Since you are using an external library at the angle you should add it at angular-cli.json

  "scripts": [
    //caminho do seu JS 
    "../assets/scripts/canvasjs.min"
  ],

Or you can use the npm install canvasjs --save importing as in the TS below and importing the script into index.html <script src="canvasjs/dist/canvasjs.js">

And for a good practice avoid using the <script></script> at the angle. canvasJS itself already supports at the angle. Example in canvasJS documentation

/*app.component.ts*/
import { Component, OnInit } from '@angular/core';
import * as CanvasJS from './canvasjs.min';
//var CanvasJS = require('./canvasjs.min');

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html'
})

export class AppComponent implements OnInit {
    ngOnInit() {
        let chart = new CanvasJS.Chart("chartContainer", {
        animationEnabled: true,
        exportEnabled: true,
        title: {
            text: "Basic Column Chart in Angular"
        },
        data: [{
            type: "column",
            dataPoints: [
                { y: 71, label: "Apple" },
                { y: 55, label: "Mango" },
                { y: 50, label: "Orange" },
                { y: 65, label: "Banana" },
                { y: 95, label: "Pineapple" },
                { y: 68, label: "Pears" },
                { y: 28, label: "Grapes" },
                { y: 34, label: "Lychee" },
                { y: 14, label: "Jackfruit" }
            ]
        }]
    });

    chart.render();
    }
}

.html

<div id="chartContainer" style="height: 370px; width: 100%;"></div>
