In this chapter, we will learn about Kibana Timelion, which works on time series data of Elasticsearch. It provides a totally different interface, through which we can chain queries, do transformations, and do visualization in a single place. Timelion provides us with a way through which we can integrate multiple data source (indices) into a single visualization. It also provides a wide range of mathematical functions that can be used on data such as sum, cumulative sum, division, derivatives, and many more.
This chapter will be very interesting. If you learn Timelion's way to interact with data, it is quite easy to deal with many available functions and apply them to create visualizations such as plotting a graph with a series on the current time against which we can draw the plot for the same data series in any other time duration...
