Internal Parameters

Internal parameters are stored in a graph, and thus are present in a source. Internal parameters are useful for parameterization within a single graph.

Creating Internal Parameters

Internal parameters can be created in the Outline pane. Double-click the Parameters item to open the Graph parameter editor. See Graph Parameter Editor.

Externalizing Internal Parameters

Once you have created internal parameters as a part of a graph, you have them in your graph, but you may want to convert them into external (shared) parameters, so you would be able to use the same parameters for multiple graphs.

You can externalize chosen internal parameter items into external (shared) file in the Outline.

Choose the internal parameters to be externalized.
Right-click and select Externalize parameters from the context menu.
A new wizard containing a list of projects of your workspace opens. The corresponding project is offered as the location for this new external (shared) parameter file. The wizard allows you to change the suggested name of the parameter file.
After that, the internal parameter items disappears from the Outline pane Parameters group, but at the same location, there appears the newly created external (shared) parameter file which are already linked. The same parameter file appears in the selected project and it can be seen in the Project Explorer pane.
