I have event document pairs that each one shows the start or end of an event. Every two events have a key with the save value.  
for example:  
doc1:  
{  
startTime: 123  
endTime: 0  
buildId: ABC1 (shared ID)  
}

doc2:  
{  
startTime: 0  
endTime: 124  
buildId: ABC1 (shared ID)  
}

I want to create a chart in Kibana to show processing of events, something like this:  
. . . .\_\_\_\_ . . . . . . \_\_\_\_\_\_\_\_\_\_  
. . . |. . .| . . . . . | . . . . . . .|  
\_\_\_ |. . .|\_\_\_\_\_\_ | . . . . . . .|\_\_\_\_\_\_\_\_\_\_\_\_

Note: It's possible for two separate events (document pair) to occur in a shared time frame. So I DONT need separation in the graph and shows the processing times are enough for me.

I appreciate tips to find a solution for this requrement.

Thanks guys.
