We recently looked at using Live data widgets to watch the daily ticket flow. We noticed that the default time settings in the widgets were too long for our needs and have recently tried to identify a way to modify the time settings in those live data widgets.
We were looking for a way to shorten the time from 30 minutes to 5-15min.
Additionally, when setting up our version of the live dashboard, we were looking for a way to set the group selection to a specific group(s) to minimize having to constantly select them each day or each time we open the dashboard.
There is no way at the moment in order to modify the time settings of the live data widgets I would recommend making a post in the beta dashboard builder forums here.
Otherwise for the group selections I would take a look at dashboard restrictions as a potential workaround, you can find more information in our documentation here. Let me know if you have any further questions.
