I'm working on trying to develop a way allow users to click on data points on vega graphs to create a filters, in the same way that users currently can on the Kibana native graphs. I am not having any luck with finding the function that begins the entire filtering process. Anyone know what function is called when a user clicks on a data point from a kibana native graph, or when they click apply in the the select filters to appy window?

Hi @slane  
I think you are looking for the following:

There are few example on how to apply context filters from an event. I think these example can be also applied to the click event on a single datapoint
