Completing the Content tab — Entering trend details
 

The system can count instances that fall within a time interval based on the value of a DateTime property.

Completing the Trend Definition form

To define trend fields:

  1. Leave the Field field blank.
  2. Click Configure to access the pop-up Trend Definition form.

Click Apply when done. The Details button changes to to indicate that the Trend Definition form is completed.

Field

Description
Trend

Choose an interval, Range (buckets) or Expression. Choose:

  • Yearly, Quarterly, Monthly, Weekly, or Daily — For fixed intervals.
  • Range — You can determine the ending point of a series of past time intervals, in units of days, weeks, calendar months or calendar quarters.
  • Expression — Enter an expression to define break points. If the expression results in a boolean value, enter a comparison.

Weeks correspond to seven-day intervals starting on a weekday that you specify. Months correspond to calendar months, not 30-day periods.
Use default

Click to enter a default list of intervals. You can modify the intervals and the captions.
Select a property

Select a DateTime property to be the basis of trend intervals.
Starting

Identify the a past or future date that is to be the latest date for the report contents.
Trend unit

If you chose Range as the Trend field value, select Day, Week, Month, or Quarter as the unit of aggregation.
Start of week

If you choose Week for the Trend field, indicate which day the week starts on.
Enable auto caption

Select to derive the captions of each time interval on the starting date value. If not selected, you can type labels for each caption in the array.
Select caption type

If the Enable Auto Caption box is selected, select a date format. Choose Custom as the date format to enter a Java date pattern as the date format.

()

If the Enable Auto Caption box is selected, select Upper Boundary Only, Upper and Lower Boundary, or Lower Boundary Only as the locus of captions.
  add row This array controls column headings and range break points. Enter up to 30 rows.
Caption

This column appears only when Enable Auto Caption is not selected. Enter text to label the column that contains the most recent values first. Text in the second row of this array labels the column with the next most recent values, and so on.
Value

This column of integer values appears only when you select Range for the Trend field.

Enter an ascending sequence of positive integers such as 1, 2, 3, or 30, 60, 90 or 4, 10, 100. Each value marks the inclusive endpoint of an interval, where the units are indicated in the Trend Unit field.

For example, if you enter 1, 2, 3, 10 in the top four rows of this array and the Trend Unit value is Weeks, at runtime the leftmost bucket will contain results for the rows in which the DateTime property is greater than 0 weeks old and less than or equal to 1 week old (based on the Starting value). The fourth bucket will contain results for the rows in which the DateTime property value is greater than 3 weeks old but less than or equal to 10 weeks old. (In this example, rows for which the DateTime property value is more than 10 weeks old may not affect the computation, but may appear nonetheless on the drill-down details.)

Click OK to save the trend definition. Click Cancel to close the form without saving your changes.

Notes

Internally, the Pega 7 Platform stores DateTime values in Coordinated Universal Time format, informally known as UTC. For reporting purposes, the system converts internal values to the time zone of the current operator as recorded in the Operator ID data instance. This means, for example, that a work item that was resolved on Monday (by an operator working in one time zone) can appear in a report to be resolved on Tuesday (in a report presented to an operator in a different time zone).

Counts, averages, and other statistics that depend on the user's time zone will naturally vary from user to user, if they have different time zones recorded in the Operator ID instance. The physical location of the users, the time zone of the Pega 7 Platform server, and the location or time zone of the last update operator are not relevant.
