Aim : On the dashboard we are showing all the currencies summed up, therefore we have no clue how much is actually collected. We should filter on currencies and be able to select a particular currency to show in the graph.
Issue : How can I add a filtering option? Which if I change the value it affects certain charts?
On the dashboard sadly you won’t have any solution.
On the workspace, you could do what you want to achieve I guess.
You will just need to have a dropdown with the currencies and filter your chart based on that information
