Specifying time hierarchies
Time data is by nature structured hierarchically. When specifying a column with dates and times in a column selector, you have the option to change the default linear series of dates to a hierarchical view of dates in form of years, quarters, months, weeks, and days.
In the hierarchy, dragging a slider lets you change the level of detail.
In the column selector, click the arrow next to the column name.
A popover listing all columns opens. Time data columns have arrows indicating they can be expanded.
- To expand a list of time display options, click the time data column in question.
Select the hierarchy.
A time hierarchy with a slider appears on the axis.
- Click anywhere outside the popover to close it.
You get a more detailed view of the same data by selecting a hierarchy with more levels, for example, year, quarter and month. This slider also offers a middle hierarchy level.
