As it's hard to describe in title i'll try to explain in full text.
if somebody have a better title tell me.
Maybe somebody already did a Kibana plugin to do so
If i have documents with start time and stop time or duration, like phone calls and i want to see the simultaneous usage of those phone calls to see the gloabl usage across the day i need to 'draw an horizontal line' between start and start+duration for each call along the horizontal (time) axis
Did someone already did somthing like that?
