Flagging an axis with a date flag ensures that Harmoni recognizes it as a time axis and behaves accordingly. In an analysis table or a visualization, Harmoni has default settings that make it easier for you to work with time period axes.
In this article:
1. Benefits of Applying a Date Flag
When you flag a standard axis as a Date, Harmoni provides the following benefits:
- The ability to have a rolling reference based on previous x periods.
- Ability to rank by the latest period when it is plotted in the across dimension.
- When dragged as a filter, the last element is applied by default.
2. Apply a Date Flag
When data is brought into Harmoni, time data is usually automatically flagged, but if not, or you need to manually create grouped time periods, any standard axis can be flagged as a date to create a time axis. After creating your axis with time series data and while in edit mode, select the axis and from the design menu, under the flags section, click date.
- Select the axis
- Click flag from the design menu

Analysis Table
Visualize
When an analysis that includes a time axis in the across is visualized, Harmoni automatically selects a line graph. When the time axis includes more than 13 time periods, the line graph includes a time slider to help you manage large numbers of time periods.
