type: 'line',
data: data,
options: {
plugins: {
title: {
display: true,
text: 'Custom Chart Title'
}
}
}
});

This example shows how to specify separate top and bottom title text padding:
```javascript
var chart = new Chart(ctx, {
type: 'line',
data: data,
options: {
plugins: {
title: {
display: true,
text: 'Custom Chart Title',
padding: {
top: 10,
bottom: 30
}
}
}
}
});
```
