The CLOSED snapshot has many of the same configurable elements as the OPEN snapshot. The main difference is that the CLOSED poll view does not have a section for a poll question nor answer options.
The only required field for the CLOSED poll snapshot is the Headline text field. All other elements are optional.
For additional details on how to configure the CLOSED snapshot, please view the OPEN snapshot configuration pages:
