Events timeline diagram can be created and customized using EdrawMax. The tool has several unique features that let you make the timeline as per your requirement. Timelines are often used in history textbooks and biographies -- they explain what happened during a certain period of time or to a particular person, starting with the earliest event and moving forward through time. Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal to a set amount of time. As the image suggests, an event timeline is the alignment of time, a chronological statement, to define a particular chain of events or activities that happened at a particular phase.
