Filter out selected filter values
Occasionally, we would want to have a chart show everything except the values selected in a filter. For this use case, we recommend using the following SQL in your chart query.
where case when '[Filter_name|Default]'= 'Default' then 1 = 1 else not [Column_name=Filter_name] end
For the above example:
- If no filter values are selected, then all results are shown
- If one or more filter values are selected, then we show everything but those values
Happy Periscoping :)
