At the moment the way to do that is use two chart objects: 1. the bar chart where you click on a bar and 2. a table object with the details. The table with the details will be filtered when you click a bar in the bar chart. The table object will have a scroll bar if there's more data then fits the space it has on the screen.
i would suggest adding a 'calculate condition' to the table object. You can use getselectedcount() and count( distinct ) to check to see if the user has selected a filter or selected for less than x number of rows before rendering... it might help with the application flow for the user. If the calculation condition is unfulfilled you can show a message
'calculation condition' is a property of the table and other objects on the right side.
