Timelion is a data visualizer designed to work on time-series data. Timelion works on different independent data sources and can be used to integrate them in a single visualization. In Timelion, we have a relatively simple expression language that helps us to retrieve time-series data, perform mathematical calculations, and change the color, label, and other calculations in order to create complex visualizations that are difficult to create using Kibana visualization. We have a Help link in the top-right corner; we can open the function reference by clicking on the link. The following screenshot shows the function reference:
In the screenshot, we can see all available functions in Timelion and, by clicking on the function name, we can get the details, such as available parameters. We can chain these functions to get the desired visualization.
So, we will take the example...
