# Chart.js | ||

|
||
## 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> | ||
``` | ||
