I have a UK map with the regions coloured by a measure from a secondary data source. I have this map and another time series chart in a dashboard. When I click on the region in the map I want it to filter the time series chart to show just for this region. I've tried using actions but this doesn't work as when I click on the region in the map it makes the chart go blank. I would appreciate any help with trying to get this to work - I assume its something to do with the data blending on the map? I'm using Tableau v9.2.4 and have attached an example workbook.
