How do I delete all the graph vertices for a particular field?

I can deselect or disable a field from appearing in my graph. But this only applies to new vertices. The old ones remain and can be deleted one by one. I have a lot of vertices and do not want to delete them one by one. Is there no way to reset the fields in a graph without starting over from the beginning in a new graph? I would like to be able to experiment with adding different fields to my graph without having to start over or manually delete individual data points.

I don't think that this is possible right now. Do you want to create an enhancement request to our repo? https://github.com/elastic/kibana/issues/new?assignees=&labels=&template=Feature_request.md

OK I added issue 111792.
