Using Data Links to create a Drill Down


I have a time series dashboard and I want the user to click on a data point in the time series, which points to a data link, which then opens up a new dashboard with more details on that data point.
My database is based on MySQL.

How do I pass the variables from the time series dashboard in the new dashboard? I see that in the URL, the correct values are passed, but I am not sure how do I make it reflect in the new dashboard.

Thanks in advance
