Visualizations can be filtered through:
Specific filters (Text, Numeric, Time, Time Window)
Text, Time and Numeric Filtering can be applied:
Local to dashboard
Globally across all dashboards in a workbook
Additionally visualizations can be configured through their settings to ignore applied filters.
A final class of filter is the filtering across a time window. In this case only the specified window of time is displayed in a time-series visualization. Time window filters are local to a dashboard, and only one filter can be present per dashboard.
