Hi All,

I have a data for visualization which is like some states are generated for a specific ID at different time stamp.  
Now I am able to create a table with all details. Please let me know if it is possible to get the difference of time so I could plot a vertical bar chart or line chart corresponding to different ID's giving details of time spent in the system.

PFB sample data in data table having different states, state ID & time stamp for selected ID : -  
ConversationID: Ascending Conversation\_StateID: Ascending Conversation\_Status\_Desc: Ascending @timestamp per minute Count

Hi Prateek,

Kibana doesn't have anything built-in that would take the difference between documents related by an ID, but it has some scripting functionality.

Here's a link to another post where a script is used to build a metric about concurrent events. It might provide some ideas;

Another option might be the Timelion plugin to Kibana. Here's one video about it but if you search you'll find more; [https://www.elastic.co/videos/time-series-analysis-using-timelion](https://www.elastic.co/videos/time-series-analysis-using-timelion)

But this is a fairly common question. I'll try to come up with a good solution and post it back here.
