Storage

Storage allows you to store plot preferences, user-defined variables, filters, and test notes so they can be applied to other data sets loaded later in the session, and to other sessions.

You can open the Storage window from the Data Editor window in either of these ways:

Using the menu Tools > Open Storage
Using the toolbar button

The example above contains a variety of stored objects. The toolbar buttons Store Current Variables and Store Current Filters, Test Filters or Test Notes allow you to put all user-defined variables and filters from the current session into storage. They appear in the Storage window. All stored user-defined variables and filters appear here regardless of which project is open — once created and brought into storage, they remain there. If you do not delete them, they are there indefinitely. You can also store view settings with the toolbar button Store Current Data Editor Layout.

The Data Editor retains memory of your plot type settings and when reopened will display the same types of views. You can also use Store Current Data Plots to save the details of your Multiple Data Plots, such as which factors to display, line style, grid, etc.

You can double-click any item in storage to append the object to the current views. For example if you double-click a Data Editor Layout object, the current views will be replaced by the saved views. Other objects add items to the current views.

You can select Export to File to send the stored objects to a file. You might do this to move the objects to a different user or machine. Select Import from File to bring such variables and filters into storage, and use Append Stored Object to add items from storage to your current project.

Use the controls to bring the variable POWER and the filter you just created into storage.
Close the Storage window.

For a detailed description of the functionality in Storage, see Storage.
