Timelines show aggregated data as a histogram.
The following image gives an overview of the anatomy of the timeline panel.
The Timeline Overview will always span the entire date range of the Microreact Project's data, regardless of what filters are applied.

The date range can be set by typing the start and end dates, or clicking on the calendar icons and selecting a date, or by dragging the Timeline Overview endpoints.
Using the calendar icons
Using the Timeline Overview endpoints
Once a date range has defined, the selection window on the Timeline Overview can be moved around to look at the same size window over different timeframes. To drag the window, hover the mouse over the bottom part of the timeline overview until a dark box appears, and drag that box to the left or right.
The units of the timeline features can be changed using the unit button in the panel configuration menu. This can be used to adjust the width of the bars when either of the bar chart types are selected in the type menu.\
The timeline can be played to show changes over time. The unit of time can be changed, and the speed (number of seconds each unit is displayed) can be changed. If the endpoints on the Timeline Overview have been set, then the playback will continue from the endpoint onward. To begin midway through the timeline, select only the first unit of the region you wish to play.
