I'm pretty new to Tableau, using Tableau Desktop 8.2
I have mutliple data sources and am looking to have filters apply to all sheets within the dashboard when a filter is changed.
Following the steps in this Tableau KnowledgeBase article, I was able to accomplish this.
However, when I add the newly created parameter/calculated field filter to the dashboard, I no longer get the option to filter on "all".
So, when I just used regular filters in the individual sheets and filtered on "Area", I saw selections for Areas 1-7 (all of them), plus an option for All, which essentially removes the filter and shows the results for the entire network, right?
Now, however, I am forced to choose one of the seven, eliminating the ability to view results for the full network.
Any ideas on what I am missing? Thanks for any help.
(I literally followed the exact steps in that article, so sorry for linking instead of describing my process- hope that's ok.
