# Chart.js [![slack](https://img.shields.io/badge/slack-Chart.js-blue.svg?style=flat-square&maxAge=600)](https://chart-js-automation.herokuapp.com/) ## Installation You can download the latest version of Chart.js from the [GitHub releases](https://github.com/chartjs/Chart.js/releases/latest) or use a [Chart.js CDN](https://cdnjs.com/libraries/Chart.js). Detailed installation instructions can be found on the [installation](./getting-started/installation.md) page. ## 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](./getting-started/usage.md) ```html <canvas id="myChart" width="400" height="400"></canvas> <script> var ctx = document.getElementById("myChart").getContext('2d'); var myChart = new Chart(ctx, { 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 } }] } } }); </script> ``` ## Contributing Before submitting an issue or a pull request to the project, please take a moment to look over the [contributing guidelines](https://github.com/chartjs/Chart.js/blob/master/docs/developers/contributing.md) first.
