Regularly, people are asking about how to implement cross filtering between multiple panels within the same Grafana dashboard.
Map Panel vs. Graph Panel
Introduction
@wtf just asked again about how we could implement cross filtering between a regular Graph Panel and the Panodata Map Panel for Grafana.
Thoughts
He would like to use a Graph Panel as a slider control element in order to interactively apply a filter on the selected timestamp to the markers displayed within one or multiple Map Panels on the same Grafana Dashboard.

GitHub - dc-js/dc.js: Multi-Dimensional charting built to work natively with crossfilter rendered with d3.js has a nice example of cross-filtering between map and graph. See also dc.js - US Venture Capital Landscape 2011.
Wait, wait … I like to highlight that these two requirements might be similar, but different on what should happen in the background:
My thoughts are based on the “shared tooltip”-function; so I want already in the dashboard loaded data (from a time-series) to be displayed in a single-point-in-time-display-panel (map or single-stat), depending on the hovered moment-in-time from one of the other panels.
The discussion I get here seems to imply that the interaction with a panel will result in a new request against the database.
