A View does not contain or store data, but provides a way for data to be manipulated and shared with users or a groups of users in different Spaces.
Think of a View as a layer that is placed on top of data before it is explored. Views provide a way to:
Go to the Views page and click Create new View, select the Source either an existing Dataset or another View.
It can be useful to layer Views on top of Views. For example, obfuscate contact data across an entire Dataset and save that as a View, then use that View as a source for multiple Views one filtering rows for the Eastern region Space and another View for Western region Space etc.
Right-click an existing Dataset or View from their list screen and select Create new View or alternatively select multiple Datasets and bulk create a View for each of them.
Views contain a list of actions that have been applied to the data.
A View can have the Interactivity value Static or Interactive, with the default being Static. Interactive Views allow users to drill down into the underlying rows that make up the aggregated data that has been shared.
There is a warning shown when sharing an interactive View that the user is sharing access to the underlying data.
Once Published, a View can be shared with some or all Spaces. In the Space where the View is included (shared to), the list of actions applied to the View is hidden, so the users of that Space cannot see the state of the data before it was filtered, grouped, obfuscated, etc.
If the Dataset has Data tags flagged as 'Sensitive' then all of the Columns tagged as containing sensitive data are highlighted before data is shared across Spaces.
Once a View has been Shared, go to Views and click Include from another Space to see a list of all shared Views. To revert this, go to the Views list screen and select Actions > Remove from Space
A Chart is just a View that ends in a Chart action, so shows a graphical representation of the data.
