Data source selector
In the dataset created for this dashboard the source of the publication was also available. In this dashboard we had three different sources for publication data. A publication could be mentioned in multiple sources and CWTS requested that we could also filter on source.
The default filter in Tableau includes or excludes an entire row, depending on the dimension or value selected. In case a publication appears in multiple sources we couldn’t just filter a specific source because that would mean I also filter out rows that to occur in other sources.
The working of the filter requested was that only the publications in the selected sources are shown and the rest is filtered out. I solved this by using a parameter action in combination with a filter.
