Get the coordinates fo the click event ( Jupyter notebook)

I think this is what you’re looking for: Interactive Visualizations

The dcc.Graph component has four attributes that can change through user-interaction: hoverData , clickData , selectedData , relayoutData . These properties update when you hover over points, click on points, or select regions of points in a graph.

This is what click data returns when you click on the point:

{
  "points": [
    {
      "curveNumber": 1,
      "pointNumber": 0,
      "pointIndex": 0,
      "x": 1,
      "y": 3,
      "bbox": {
        "x0": 189.35,
        "x1": 209.35,
        "y0": 888.72,
        "y1": 908.72
      },
      "customdata": [
        3
      ]
    }
  ]
}

This works only if you click on the point/object. I am not aware of methods that can allow to get data from clicks anywhere on the graph.
