====Using Timeline====

===Step 1: Open Timeline and Enter Dates===
{{ :timeline:timelinesidebar.png?200|}}
Open the Timeline page in the side-bar of your ARDI server.

Pick the date range you'd like to run Timeline across. Normally, this should be a span of time (ie. 10 minutes, on very fast processes) before an event.

Timeline gives you two options for entering a time. 

You can either use the first box, where you enter a **time** (the time the event happened) and a **span** (the amount of time before the event you'd like to inspect)

Or you can use the second box, which allows you to choose a specific start and end time.

===Step 2: Wait for Data Analysis===

After pressing 'Search for Events', you will need to wait some time for the data extraction process to begin. 

Note that this happens every time you choose a different time range to analyse with Timeline, as all of your points of data are downloaded for analysis. 

===Step 3: Review Data===

Once the analysis is done, you'll have two ways of looking at your information.

The [[event list]] is great if you want to know //what// happened, but don't particularly care about //when//.

The [[timeline]] is more suited to finding out //when// each event happened. 

===Step 4 (Optional): Update Patterns===

Timeline shows you //events//. It doesn't mean that these are unexpected or even important events - many of them will be a standard part of  your systems operation.

To help you remove all of the known and expected events from your timeline, we include [[pattern matching|pattern recognition]]. You can tell Timeline that certain combinations of events indicate known and expected actions on your plant.
