Filters and contexts are used to show the report or analysis with a subset of the response data. There are two types of filters and contexts available to use in Snap Online:

  • External filters and contexts. These are defined from the Analyses or Reports windows in Snap Desktop. Once defined, the filter or context can be applied to reports and analyses in both Snap Desktop and Snap Online. These are available as part of the survey and can be used every time the survey is opened.
  • Custom filters and contexts. These are set up in Snap Online using a filter expression. You can use the variables section to check the variables and questions used in the questionnaire to help create the expression. These are temporary filters and contexts that are available while the survey is open but are removed when the survey is closed.
