Filter interaction with chart

[denispillay]

i have 1 filter pane and 1 bar graph 

in filter pane have zone values (africa, india, japan, canada, Uk , Austrelia, N/A)

without any selection only (africa, india, japan, canada, Uk , Austrelia) profit should appear, N/A should not be there 

but when i select N/A from filter pane N/A then bar graph should show sales of N/A

kindly help me out

[BrunPierre]

This perhaps.

=If(GetSelectedCount(zone), Sum(Sales), Sum({<zone-={'N/A'}>} Sales))

[denispillay]

can you pls describe in detail pls

how i should apply 

[BrunPierre]

That should be the bar chart expression, where "N/A" is excluded by default but included when the user explicitly selects it or other zones.

and what about other filters it will work accordingly or not
