Once you've built your visualisations, you can add dynamic filters or filter selectors to easily refine the data you want to see.
Click the selector icon to the right of the graph icon in the toolbar.
Select Attribute/Metric Selector from the dropdown.
Click the attribute or metric selector icon.
Click the blue Select Target button, then click on the report to set it as the source for the selector.
Click Apply to confirm.
Once set up, you can use the selector to filter the visualisation by the attributes you have added.
