I've recently begun using Tableau Online and cannot understand how can 2 workbooks (or more) be merged in one? I'd like to use them in the same dashboard. Or this option is not available for the Online version?
Are both workbooks using the same data source?
In relation to your question, it is not possible yet to do this in Tableau Online in your browser but you should be able to achieve this using Tableau Desktop
