| ---- | ---- | ------- | -----------
| `align` | `string` | `'center'` | Alignment of the title. [more...](#align)
| `display` | `boolean` | `false` | Is the title shown?
| `position` | `string` | `'top'` | Position of title. [more...](#position)
| `fontSize` | `number` | `12` | Font size.
| `fontFamily` | `string` | `"'Helvetica Neue', 'Helvetica', 'Arial', sans-serif"` | Font family for the title text.

| `fontStyle` | `string` | `'bold'` | Font style.
| `padding` | <code>number&#124;{top: number, bottom: number}</code> | `10` | Adds padding above and below the title text if a single number is specified. It is also possible to change top and bottom padding separately.

## Example Usage
The example below would enable a title of 'Custom Chart Title' on the chart that is created.
```javascript
var chart = new Chart(ctx, {
type: 'line',
data: data,
options: {
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: {
title: {
display: true,
text: 'Custom Chart Title',
padding: {
top: 10,
bottom: 30
}
}
}
});
```
