What is Timeline?
[[File:Taiwan historyENG2.PNG|thumb|right|300px|{{Center|A graphical timeline of the history of [[Taiwan]]}}]] A '''timeline''' is a way of displaying a [[wikt:list|list]] of events in the order they happened (called [[Chronology|chronological]] order). It may be in the form of a list or a [[graphic design]]. A [[graphic]] timeline typically shows a long bar labelled with [[calendar date|dates]] and usually events. But it can be other layouts as well. ==Uses of timelines== Timelines are often used in [[education]]. They help students and researchers understand the order or chronology of historical events for a subject.<ref>Greg Moskal, ''The History of Space Exploration: Sequencing Events Chronologically on a'' (New York: PowerKids Press, 2004), p. 25</ref> A timeline can be used to [[wikt:visualize|visualize]] the time between events, durations (such as lifetimes or wars), and the overlap of events.<ref>Wolfgang Aigner; et al., ''Visualization of Time-Oriented Data'' (London; New York: Springer, 2011), p. 166</ref> ===History=== Timelines are particularly useful for studying history, as they convey a sense of change over time. Wars and social movements are often shown as timelines. Timelines are also useful for [[biography|biographies]]. ===Project management=== Another type of timeline is used for [[project management]]. They are important to help team members to know what [[wikt:milestone|milestones]] need to be achieved. It also shows the time [[schedule]]. An [[example]] is showing a [[project]] timeline for a [[Systems development life cycle]] of a computer system. == References == {{reflist}} [[Category:Statistics]] [[Category:Diagrams]] [[Category:Time]]
