You’re right. We should do a better job documenting event data.

For what it’s worth, cartesian `plotly_hover`, `plotly_click` and `plotly_unhover` event data looks like:

```auto
{
  points: [{
    curveNumber: 2, // index in data of the trace associated with the selected point 
    pointNumber: 2, // index of the selected point
    x: 5, // x value
    y: 600, // y value
    data: {/* */}, // ref to the trace as sent to Plotly.plot associated with the selected point
    fullData: {/* */}, // ref to the trace including all the defaults
   xaxis: {/* */}, // ref to x-axis object (i.e layout.xaxis) associated with the selected point
   yaxis: {/* */} // ref to y-axis object " "
  }, {
    /* similarly for other selected points */
  }]
}

```
