Timelion visualization in Kibana
When we want to compare data related to time, Timelion is used. We have a blog, for instance, and we get our views every day. We want to evaluate the data in which we want to equate the information of the current week with that of the previous week, i.e. Monday-Monday, Tuesday-Tuesday and so on, how the thoughts and even the traffic varies.

Configuring Timelion Function
In Kibana Management ⁇ Advanced Settings, the timelion setting is completed.
Press Advanced Settings, and from the Category, pick Timelion.
After Timelion is selected, all of the necessary fields necessary for Timelion configuration will be displayed.
We can adjust the default index and the time field to be used for the index in the following fields -
The default one is all and @timestamp is the time area. We 'd keep it as it is and in the Timelion itself, modify the index and Timefield.
Data Visualization using Timelion
Index: medicalvisits-26.01.2019. We can need it. The data shown from Timelion for 1 January 2017 to 31 Dec 2017 are as follows:
The expression used for the show above is as follows:
.es(index = medicalvisits-26.01.2019,timefield = date of visit).bars)
We have used the index medicalvisits-26.01.2019 and the timefield is Visiting-Date and the bars feature used on that index.
We have evaluated 2 towns for the month of January 2017, day wise, in the following.
The term used is -
.es(index = medicalvisits-26.01.2019,timefield = date of visit,
Q = City: Sabadell).label(Sabadell),.es(index= 26.01.2019 patient visits,
Timefield = Date of visit, q = City: Terrassa).label(Terrassa)
The 2-day timeline comparison is seen here.
.es(index = medicalvisits-26.01.2019,timefield = Visiting Date).label("2nd August 2018),
.es(index= medicalvisits-26.01.2019, timefield= Date of visit, offset=-1d).label("1st August 2018)
We have used offset here and given a 1-day discrepancy. The present date has been selected as 2nd August 2018. So, for 2nd Aug 2018 and 1st Aug 2018, it gives a data gap.
The list of the top 5 data for January 2017 in the cities is shown below. The keyword that we have used in our visualization is given below.
.es(index = medicalvisits-26.01.2019,timefield = date of visit, split = city.keyword:5)
Here in the field options of the visualization we have used the split and have given the field name in the fields as city and we gave it as split = City.keyword:5 because in our visualization we need to show the top five cities from the index. One can select the fields as per his needs and choices, and can change the fields accordingly.
It gives each town's count and lists their names as seen in the plotted graph.
