Creating and configuring timelines
Like flowcharts and brainstorm diagrams, you can also create timelines in Visio to represent a timeline or a series of events.
Creating a timeline
To create a timeline, go to the New menu in the File tab and click Templates. Go to the Schedule category, click Timeline, and then click Create to create the timeline workspace. Since timeline is primarily a measure of time, selecting units is irrelevant.
Setting up a timeline shape
Once the timeline template is created , click and drag the block timeline shape from the Shapes pane onto the canvas.This opens a Configure Timeline dialog box, where you can select the duration of the timeline.ie and the timescale. Click on Ok.
It creates a timeline block with equal intervals between the selected dates.
