```auto
var gd = document.getElementById('graph')
Plotly.newPlot(gd, [], {})
gd.on('plotly_click', () => {})

```

should do the trick.

Ha, we don’t expose a way to that at the moment.

You can subscribe to [https://github.com/plotly/plotly.js/issues/145](https://github.com/plotly/plotly.js/issues/145) for the most up-to-date development info.
