In addition, you can choose how many timescales you want to use as well as the width of each period in the timescale.Ĭhanges you make to the timescale apply only to the active view, but those changes become a permanent part of that view definition. You can also display a calendar or fiscal year. For each timescale, you can customize the units, the labels for time periods, and the label alignment. You can display up to three timescales in a view. The timescale is a prominent feature in many Microsoft Project views, such as Gantt chart and usage views.
