Creating a Chart

It's easy to get started with Chart.js. All that's required is the script included in your page along with a single <canvas> node to render the chart.

In this example, we create a bar chart for a single dataset and render that in our page. You can see all the ways to use Chart.js in the usage documentation

1. <canvas id="myChart" width="400" height="400"></canvas>
2. <script>
3. var ctx = document.getElementById("myChart").getContext('2d');
4. var myChart = new Chart(ctx, {
5. type: 'bar',
6. data: {
7. labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
8. datasets: [{
9. label: '# of Votes',
10. data: [12, 19, 3, 5, 2, 3],
11. backgroundColor: [
12. 'rgba(255, 99, 132, 0.2)',
13. 'rgba(54, 162, 235, 0.2)',
14. 'rgba(255, 206, 86, 0.2)',
15. 'rgba(75, 192, 192, 0.2)',
16. 'rgba(153, 102, 255, 0.2)',
