You can access this type of filter in the dashboard's Filters panel, which also shows any applicable global filters  that are turned on.

To edit a dashboard filter (e.g., select a different member)

After opening the Filters panel, tap on any filter to edit it; then, choose one or more members to filter on them. Tap on Done and then Apply.

To show data for all members (i.e., ignore the filter), leave it set to "All" in the filter panel.

Tip: To filter out data for the selected member(s) rather than including data for those members, you can turn on the Exclude option at the bottom of the filter menu.

To add a dashboard filter

In the Filters panel, go to the Collections area; then, apply or create a collection. 

To clear or remove a filter

In the Filters panel, tap the X to clear a dimension or key filter (i.e., show data for all members).

Tap the trash icon to completely remove a filter. Key and dimension filters must be cleared before you can remove them.

Tip: You cannot remove a filter if it has a corresponding filter widget in the original dashboard.

You can save and reuse sets of dashboard filters.

When you load saved filters, only applicable filters will be used (i.e. dimension is used as a group by in the dashboard).
