One of the great features of Tableau is the ability to create "Actions." What you are asking for is a "Filter Action." One of my earliest blog posts was about them. Enjoy!!!
Sir you are a Legend! Thanks so much. You just made my report 10 times more useful!!
what if there are more than 15 data sources and over 50 sheets to be filtered with actions? I use action filters to be able to filter all dashboards with 2 map selections. however it takes very long time to apply these filters thru actions to over 50 sheets.
any idea how a map based global filter can be applied to reduce the response time?
Have you been able to get the actions to work with map plots? This doesn't seem to work the same way it would with a different visualization (pivot, bar, etc). Is there an extra step that needs to take place to allow map plot selection to be applied to other sheets/dashboards?
