With linked filters, you have the ability to edit the same filter present across multiple gauges.
When you have a filter on a gauge, you’ll be able to convert that filter to become a “Linked Filter” by clicking on the plus icon.
When you click on the plus icon, you’ll be prompted to give the linked filter a name and decide which gauges (or gauge layer) you want to apply it to
Once you press create, the linked filter will be added to all the gauges you selected! And your filter will change to a different color (blue). You can click on the edit icon to launch that same modal to change the name and edit which gauges it's on.
Once you have a Linked Filter created, on any new gauge (or gauge layer) that has that dataset, you’ll be able to add the Linked Filter.
And on any gauge you change the filter or filter value, it will update all the gauges using that linked filter.
A couple of important rules to note:
- A gauge must be saved with the filter you want to turn into a Linked Filter.
- If you change the filter value without saving a gauge of a linked filter, the filter will not update on other gauges. Essentially meaning if you change the value of the filter of a Linked Gauge, other gauges won’t get updated until the gauge is saved.
- If you remove a Linked Filter from a gauge, you can always re-add it.
- You can delete a Linked Filter from the edit modal. This would remove the filter from all the gauges it's on.
