One Click Filters
Users currently brush charts by selecting a data point and including / excluding results via a menu option. To improve the user experience, report consumers should be able to interact directly with the visualisation and cross-filter / highlight at either the visualisation, report or dashboard levels through a single click.
For example, if a user clicks on an x-axis data point in a bar chart, that selection automatically applies that categorical value as a filter to the dashboard. Deselecting would then return the dashboard back to its prior state.
This functionality could be switched on / off in the chart settings menu and / or an option added to exclude the visualisation from any filters applied by another chart.
