Snapshots are static representations of the state of an object from one Qlik Sense application at a certain point in time. A snapshot is a copy of that object, even though the original object might have been deleted or changed, or the underlying data reloaded. The snapshot keeps the context, format, and value of the original object.
For every Qlik Sense object, any changes made to the filter pane and the extensions can be captured as a snapshot in a very simple and intuitive way. When you place your cursor over the object, an icon with a camera appears, which looks like this:
When you click the icon, the object's state is captured and a form is displayed, giving you the opportunity to describe the snapshot using an annotation, as shown in the following screenshot (this is very useful for organizing your snapshot library):
