How do you use filters or change settings on your questions/cards?
If you want to filter all cards in a report, the best way is to use the report filter, that you can learn more about here.
If you want to filter a card or change the card settings, for example graph type, the card name or if you want to remove the card, press the "edit" button in the top right corner:
When you press "edit", the card modal where you can change settings and filters appear:
Press "add filter" for filtering, and then choose what type of filtering you want to do (for example based on date or answers):
After that, you specify the filter in the right box, for example choosing a date span as in the image above. When you have selected your filter, the card will be updated automatically.
The card modal can also be used to change graph type by simply pressing the graph type you want. You can also change the card name, add a description, duplicate the card or delete it.
