Question about legend item selection


I Don’t know if it’s possible but I would like to be able to click on one item in the legend of a graph and have all the graphs and widgets update not just the current graph.
For example i have 2 graphs and a pie chart and clicking in the first one on one item would update the second graph and the piechart into displaying information(or not displaying anything, if that’s the case) regarding the item i clicked on in the first graph’s legend.

Also, is it possible somehow to link between dashboards ? say clicking on a legend item of a graph on DASHBOARD_A opens a dashboard specific for that item alone with statistics and whatever else i chose to populate the new dashboard with ?
