I can find a lot of threads on how to link widgets (indicators, charts, etc.) to the current map extent but I cannot see how to apply the solution in Operations Dashboard in AGOL. Has this feature been implemented yet? Thank you!
Yes, this has been implemented. After you've added your map and other widgets, open the action configuration dialog for the map.
Then select the map in the dropdown. When extent changes, you can configure the extent to filter other widgets such as a serial chart.
Then click Done and Save the dashboard. When you pan or zoom the map, the widgets should update their values.
