I have several dashboards and would like to keep the same time searching period when navigating from one dynamic dashboard to another. What would be the best approach for something like this?
are you speaking about drilldown?
if you want to pass the time period from a dashboard to another you have to insert in your drilldown url the two tokens, something like this:
and in the secondary dashboard you have to insert the two time tokens in earliest and latest tags
Just add a timepicker, give it a default value and reference it inside of each of your panel's searches. If you would like it to not be alterable, then make the control invisible.
