# Subtitle
Subtitle is a second title placed under the main title, by default. It has exactly the same configuration options with the main [title](./title.md).
## Subtitle Configuration
Namespace: `options.plugins.subtitle`. The global defaults for subtitle are configured in `Chart.defaults.plugins.subtitle`.
Excactly the same configuration options with [title](./title.md) are available for subtitle, the namespaces only differ.
## Example Usage
The example below would enable a title of 'Custom Chart Subtitle' on the chart that is created.
```javascript
var chart = new Chart(ctx, {
type: 'line',
data: data,
options: {
plugins: {
subtitle: {
display: true,
text: 'Custom Chart Subtitle'
}
}
}
});
```
