|
||
|
|
| `onHover` | `function` | `null` | Called when any of the events fire. Called in the context of the chart and passed the event and an array of active elements (bars, points, etc).
|
||
|
|
| `onClick` | `function` | `null` | Called if the event is of type `'mouseup'` or `'click'`. Called in the context of the chart and passed the event and an array of active elements.

|
||
|
|
## Event Option
|
||
|
|
For example, to have the chart only respond to click events, you could do:
|
||
|
|
```javascript
|
||
|
|
var chart = new Chart(ctx, {
|
||
|
|
type: 'line',
|
||
|
|
data: data,
|
||
|
|
options: {
|
||
|
|
// This chart will not respond to mousemove, etc
|
||
|
|
events: ['click']
|
||
|
|
}
|
||
|
|
});
|
||
|
|
```
