Non functional pie chart

[#1]

Hi,

I´m using a pie chart to illustrate vacancy in properties. To do this I´m using a calculated dimension:

if(Match(CONTRACTS, 'Vacant'), 'Vacant', 'Rented')

- Everything works fine except that when clicking on Rented in the pie chart I can see the contracts but I cant click myself back by clicking on the chart again. Which makes me unable to see the vacancy again.

How can this be fixed?
