# Events
The following properties define how the chart interacts with events.
| Name | Type | Default | Description
| ---- | ---- | ------- | -----------
| `events` | `string[]` | `['mousemove', 'mouseout', 'click', 'touchstart', 'touchmove']` | The `events` option defines the browser events that the chart should listen to for tooltips and hovering. [more...](#event-option)
| `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']
}
});
```
