Use the time picker on the Time toolbar

The time picker allows you to select a time range by specifying a start time, end time, and/or duration.

An error appears next to the start or end time controls if you specify an invalid time period. For example, an end time before a start time.

To specify a time period

1. On the Time toolbar, specify the start time, end time, and/or duration. To select a date from a calendar, click the down arrow on the start time or end time field. To select a predefined duration, click the down arrow on the duration field.

   

   When you change one of the fields, one of the other fields is recalculated automatically. When you select a field, a blue frame appears around the field that will be recalculated as a result of the change.

   The relation between changed and updated times is as follows:

   You change...	The time picker updates...
   Start time	End time (based on duration)
   End time	Start time (based on duration)
   Duration	Start time (based on end time)

   If you change multiple time fields in a row, which field is updated depends on which two other fields you changed last. For example, if you change the start time and then the end time, the duration is calculated accordingly. If you change the start time and then the duration, the end time is calculated, and so on.

2. Press ENTER.

To specify a time period relative to the current time

3. Do one of the following:

   • On the Chart menu, click Update to Current Time so that a check mark appears.

   • Click the Update to Current Time toolbar button so that it is highlighted.

4. In the duration list of the Time toolbar, click a duration or type one manually.

   The start time is automatically calculated as the current time minus the duration you selected, and the trend display is updated with the new time period.
