Collecting insights for stories using snapshots
To get your app's full picture, you need a way to collect the insights you encounter. To do this, you take static snapshots of your visualizations.
A snapshot is a graphical representation of the state (type and data) of a data object at a certain point in time that you can use when you build stories. The snapshot you take is a copy of the state. This means that the state of the snapshot does not change when the state of the corresponding data object gets updated.
When you take a snapshot you can make an annotation for your snapshot. The annotation helps you distinguish between the different snapshots in the snapshot library when you build your story. The annotation is not visible when you play the story.
After taking snapshots of a specific visualization, you can open the Snapshot library from the visualization's shortcut menu. From there you can decide which snapshots to keep and use in your stories. You can also edit the annotation and delete the snapshots.
If the visualization you want to take a snapshot of is an extension, make sure to enable the snapshot functionality in its main script. To do that, set the snapshot property to true.
For more information, see Allow snapshots of your visualization.
