Hi,
I'm analyzing a series of events that have a start time and an end time. I would like to plot an area chart with time on the x axis and on the y axis the number of events that are ongoing at that moment (start \< x \< end). Is this possible at the moment?
The result would be something similar to de date histograms only we count how many times x lies between two values instead of counting how many times a value lies in an interval.
Help would be greatly appriciated

It is possible, but the solution is a bit complex. It is posted in this thread: [Display concurrency in data on Kibana](https://discuss.elastic.co/t/display-concurrency-in-data-on-kibana/26006)

Thank you for the link! It seems to be the way to go. I ran into an issue with this solution. I posted it in the linked thread since it seemed better suited there.
