Answer

Change your chart.js to

<script src="node_modules/chart.js/dist/Chart.bundle.min.js"></script>

app module ts code

import { ChartsModule } from 'ng2-charts/ng2-charts';

// In your App's module:
imports: [
   ChartsModule
]

Update remove script tag in index.html and add in

check your angular-cli.json and scripts array, then inside it add:

"../node_modules/chart.js/dist/Chart.bundle.min.js"

Question 2

I am trying to use ng2-charts with Angular 4.0 and I would like to have the same thing like here by using chart.js:

    ...
    <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.6.0/Chart.bundle.min.js"></script>
    ...

    <canvas id="myChart" width="400" height="400"></canvas>
    <script>
        var ctx = document.getElementById("myChart").getContext('2d');
        var chart = new Chart(ctx, {
            // The type of chart we want to create
            type: 'horizontalBar',

            // The data for our dataset
            data: {
                labels: ["example1","example2","example3","example4","example5","example6","example7"],
                datasets: [{
                    label: "My First dataset",
                    backgroundColor: 'rgb(255, 99, 132)',
                    borderColor: 'rgb(255, 99, 132)',
                    data: [0, 10, 5, 2, 20, 30, 45]
                },{
                    label: "My second dataset",
                    backgroundColor: 'rgb(2, 99, 132)',
                    borderColor: 'rgb(255, 99, 132)',
                    data: [3, 10, 5, 2, 20, 30, 45]
                }]
            },

            // Configuration options go here
            options: {
                scales: {
                    xAxes: [{
                        stacked: true
                    }],
                    yAxes: [{
                        stacked: true
                    }]
                }
            }
        });
    </script>

What I have done is

npm install ng2-charts --save
npm install chart.js --save

and I have added

<script src="node_modules/chart.js/src/chart.js"></script>

to src/index.html

and

import { ChartsModule } from 'ng2-charts';

imports: [
   ChartsModule
]

to src/app/app.module.ts

Can you show me an working example of src/index.html, src/app/app.component.html and app/component.ts for it? Because I have some problems with it like in example

GET 
http://localhost:4200/node_modules/chart.js/src/chart.js [HTTP/1.1 404 Not Found 8 ms]
ERROR Error: "undefined" is not a chart type.

even if I change the chart.js location.

src/index.html

<!doctype html>
<html>
<head>
  <meta charset="utf-8">
  <title>Chart</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">

  <script src="../node_modules/chart.js/src/chart.js"></script>

</head>

<body>
  <app-root>Loading...</app-root>
</body>
</html>

src/app/app.component.html

<h1>
  {{title}}
</h1>

    <div style="display: block">
      <canvas baseChart
              [data]="chartData"
              (chartHover)="chartHovered($event)"
              (chartClick)="chartClicked($event)"></canvas>
    </div>
    <button (click)="randomize()">Update</button>

src/app/app.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app works!';

  public chartData: Array<any> = [
    [65, 59, 80, 81, 56, 55, 40],
    [28, 48, 40, 19, 86, 27, 90]
  ];

}
