Timelion is a time series data visualizer that enables you to combine totally
|
|
independent data sources within a single visualization. It's driven by a simple
|
|
expression language you use to retrieve time series data, perform calculations
|
|
to tease out the answers to complex questions, and visualize the results.
|
|
|
|
For example, Timelion enables you to easily get the answers to questions like:
|
|
|
|
* How many pages does each unique user view over time?
|
|
* What's the difference in traffic volume between this Friday and last Friday?
|
|
* What percent of Japan's population came to my site today?
|
|
* What's the 10-day moving average of the S&P 500?
|
|
* What's the cumulative sum of all search requests received in the last 2 years?

== Creating Time Series Visualizations
|
|
To start building time-series visualizations, click **Timelion** in the side
|
|
navigation and run through the tutorial. Documentation for the Timelion
|
|
expression language is built-in. Click **Docs** in the toolbar to view
|
|
the available functions and access the tutorial. As you start to enter
|
|
functions in the query bar, Timelion displays the available arguments:
|
|
|
|

|
|
|
|
To incorporate a Timelion visualization into a Kibana dashboard, save the
|
|
Timelion expression as a Kibana dashboard panel. You can then add it to
|
|
a dashboard like any other visualization.
|
|
|
|
TIP: You can also create time series visualizations right from the Visualize
|
|
app--just select the Timeseries visualization type and enter a Timelion
|
|
expression in the expression field.
