Marker with number in highcharts

Question

I have a scatter plot where some of the values are so close to each other that only one marker is drawn. Is there a way to indicate that there a re more then one entry on this place. I'd like to add a number with items on this location.

Answer 1

You can catch datalabels.formatter and use loop on each series / and each point to check if any points has the same coordinates. Then sum it and return in the funcion.
