Date Time Variable Settings
When preparing a table or plot of a Date/Time variable, Displayr automatically examines the data to make its best guess as to the appropriate time unit of analysis (e.g., weeks, months, quarters).
Buttons, options and fields
Aggregation The level of aggregation of the data. For example, if Week is selected, the data is shown as weekly data.
Period type The range of dates to be displayed.
- All Data All the dates in the data file. Natural periods will be used. For example, if Aggregation is 1 Month then whole calendar months will be used, even if the data does not end exactly on the end of the month.
- Date Range Limit the variable to dates between the specified Minimum and Maximum. The last period will end on your maximum date, and periods will be calculated back from then. For example, if you provide a date range from 2 Mar 2017 to 27 May 2017 then the periods will be 28Feb..27Mar, 28Mar..27Apr and 28Apr..27May. If you want round months then choose Maximum at the end of the period (e.g. the end of the month).
- Duration The number of time periods to be displayed. Natural periods will be used. For example, if Aggregation is 1 Month then whole calendar months will be used, even if the data does not end exactly on the end of the month.
