To view city/country/state geographically, make sure that you double click on the same dimensions and not dragging and dropping, as in your workbook its already showing all 3 dimension in geographical role only.
Hope this will resolve your issue.
Once I had same problem only with City role. Try to reinstall Tableau Desktop and delete remaining files in folder, when you uninstall it
Thanks for your reply.
I have tried all the points which have been suggested by you guys.
I am able to change the dimension role to geographic in Tableau 9.3 somehow I am not able to do this in Tableau 10.0
I don't think its a workbook issue, as I have used same data source in Tableau 9.3 and was able to change the geographic role.
I will try to uninstall and re-install Tableau 10.0.
Thanks Again !!
I am using 10.0 only. So, U think that should not be the case.
