Setting the Time Window

The setting of the DSSVue Time Window determines how much of each selected dataset will be used or impacted when viewing or editing. To set (or unset) the DSSVue Time Window you can either:

• Select Time Window...from the Display menu, or

• Click the Set Time Window button. The Set Time Window editor will be displayed ("Figure: Set Time Window Editor").
  

  Figure: Set Time Window Editor

The Set Time Window editor has four radio button options to choose from for setting the time window:

• No Time Window—this option clears the Time Window setting. When no Time Window is set, all the data in the selected datasets will be used or affected by the actions you take on them.
• Specific Time Window—this option requires that you enter specific Start and End Dates and Times to define the time window. Dates are entered in DD MMM YYYY format. Times are entered using a military 24-hour clock (e.g., 3:00 pm is 1500).
  •  The  button—in any date field can be used to open a Calendar tool for selecting a specific date.
  • Clear—clears the time window fields of any prior settings.
  • Set Current Time—uses the system time on your computer to fill in the Start and End dates and times.
• Relative to Current Time—this option uses the system time of your compute to determine a time window. The parameters for this option are:
  • Go Back—a time interval from the drop-down list and then enter the number of intervals backward in time to set the start of the time window.
  • Go Forward—select a time interval from the drop-down list and then enter the number of intervals forward in time to set the end of the time window.
• By Individual Water Year—this option will cause DSSVue to act on the selected datasets in Water Year chunks. This means that if data in a selected data set starts before the start of the Water Year or extends beyond the end of a water year, then the data outside a water year boundary will not be included in the "Time Window".
  • Start Date of Water Year—enter a date that defines the start of a water year for your data; this date is in the form DD MMM, a year is not required.
    If you activate (check) the Retain Between Sessions checkbox, DSSVue will remember your Time Window settings between executions of DSSVue. If unchecked, the default of No Time Window will be used each time DSSVue is launched.

NOTE: When DSSVue is opened from the Simulation module of ResSim, ResSim sets the DSSVue Time Window to the time window of the active Simulation.
