Setting a time range in Activeboards
You can use the general time-range control in the Activeboards work area to enable real-time by clicking the play button, or apply a time range to all the widgets in your Activeboard. Alternatively, you can assign a specific time range to an individual widget by clicking on its top bar and setting the time range in the pane to the right.
Learn the basics of setting an absolute or relative time range in your Activeboard or specific widget in the following video:
Set a time range for your Activeboard
When you set a specific time range for an Activeboard, the widgets' data is automatically recalculated and only the results for the selected time range are displayed.
Simply click the time-range area in the top-right corner to define a new period in the window that appears, then click Apply to recalculate the Activeboard's data.
Set a time range for a widget
You can also set specific time ranges for individual widgets by clicking the widgets' top bar and enabling the Custom Date Range option. This will open a time-range picker that works exactly the same as the Activeboard general one. Remember that setting a custom time range for a widget overrides the period selected for the Activeboard.
Keep in mind that selecting the ISO week option for a snap to time range means that your week begins on Monday. By default, the week in Devo always begins on Sunday. If you use the platform in Spanish then your week begins on Monday by default.
Absolute, relative and snap-to time ranges
There are three different options available when you set a time range for an Activeboard or widget:
Set an absolute date
Click the time range indicator and select the start and end date of your required range, then click Apply. The Activeboard or widget will be updated to display data from that period of time, and the selected range will be shown in the time range indicator.
Set a relative date
You may want to represent data from periods of time relative to the current date (for example, last 5 minutes, last day, etc.). To do this, click the time range indicator and select one of the options in the Preset intervals area on the right, then click Apply.
The interval selected will be shown in the time-range indicator. You will notice this icon, which indicates that a preset interval has been applied to the Activeboard or widget.
When you select a relative date, you can click the play button to activate real-time data flow in your Activeboard or widget. After activating the real-time option, this iconappears on the corresponding widgets. Keep in mind that widgets with a custom date range set will not be affected when you enable this option in the Activeboard time range selector.
When the real-time option is enabled, widgets are refreshed at the query grouping time (for grouping time > 0 and <= 5 minutes) to show the new data corresponding to the relative period specified. Widgets with queries that group data every 0 (no-temporal grouping), or queries that don't group data or grouping time is greater than 5 minutes, are refreshed every 15 seconds.
For example, if you select Last 5 minutes in a widget custom time range and the widget query groups data every 5m, the widget will be refreshed every 5 minutes to show data corresponding to the last 5 minutes. If you select Last 5 minutes in a widget custom time range and the widget query groups data every 10m, the widget will be refreshed every 15 seconds to show data corresponding to the last 5 minutes.
Set a snap to date
With this option, the selected time range rounds down to the beginning of the current time period. For example, if it is 10:53 on a Tuesday and you snap to day, you will see data beginning at 00:00 on that same Tuesday. If it is 10:53 and you snap to hour, you will see data beginning at 10:00. Breaking it down further, if it is 10:53:17 and you snap to minute, you will see data beginning at 10:53:00.
Click on the time-range indicator and click on the snap to tab. Choose from one of the preset interval options on the right, then click apply.
The interval selected will be shown in the time-range indicator. You will see this icon
When you snap to a selected time, you can click the play button to activate real-time data flow in your Activeboard or widget.
