I am not sure I understand your statement about the parameter control being used "so that my eventual dashboard is able to show the 3 main statistics I want from the same country from different data sources". Can you further explain why you are using a parameter instead of a Cross DB filter? What version of Tableau are you using?
With more detail, I may be able to assist. Its still a bit hard for me to understand the use case right now, or what the purpose of the parameter vs. a filter is. Can you mock up your expected results, or further explain what you hope to happen once a Country is selected?
Hi Matt! I am on Tableau 10.1. The three graphs you see below are from varying database, and the parameter control helps me to unify the country column as i couldn't get the Union function to work with my database.
This is what I have built so far:
1) I have a "Country Select" Parameter that allows me to switch to any country and the corresponding graphs will switch the country too. This is my "Parameter Control"
2) I am trying to insert a Seperate "Filter" that will allow me to add additional line Graphs onto "Real GDP Growth" portion, something like this, white retaining my Parameter Control so that users, while exploring the specific country detail (for example U.K), can compare the GDP Growth of another country with ease.
Hope I am clearer this time round. I am still working to find a work around that will enable be to achieve this function for my end-users.
If it is convenient for your users
to have another "Country" filter on a dash --
with the "(Selected Country)" value in it
instead of the actual name of the Country
being selected from the Parameter --
then the attached would be of some help.

Thanks Yuriy. I got it to work with my Dashboard.
Eric, you're welcome.
