In this chapter, we covered Kibana Timelion features and expressions, through which we can create graphs. There were different styling functions, which can be applied to make graphs more effective and meaningful, such as .color() and .label(). Apart from styling functions, we also discussed other mathematical functions, which can be used to perform various mathematical operations on series data.

Furthermore, we covered various data sources such as Elasticsearch, static, and the World Bank and how we can use them for creating graphs. These data sources provide us the functions through which we can directly use their data into our graphs.

We also covered how to use the offset parameter to plot time difference graphs for getting instant information about how data has evolved over time and through which the management can take decisions. We also explained the GDP trend through offset parameter by taking the World Bank data source.

Then, we covered various options that we can use in Timelion...
