# Stream Graph

The Streams tab lists streams while the Stream Graph tab displays a graphical representation of the relationships between parent and child streams in a selected depot.

To display streams in the Streams tab:

1. Go to View > Streams to open the Streams tab.

2. Select a display option by clicking the Show streams in List or Tree icon:

   - List displays the streams in a flat list.
   - Tree (default) displays the streams in a hierarchy, with development streams and release streams listed under mainline streams.

3. Search for streams or restrict the streams that are displayed by using the Filter pane at the top of the tab. You can filter by owner, stream name, parent stream, stream type, and depot.

   For more information about filters, see Search and filter.

## Display streams in the Stream Graph tab

1. Go to View > Stream Graph to open the Stream Graph tab.

2. Select a display option by clicking the Show streams in Picker or Filter icon .

   The View menu also lets you Show Stream Graph As either Picker or Filter.

When you select a stream, it is highlighted in both the left pane's hierarchical view and the right pane's stream graph. You can navigate with either pane, and the two panes remain in sync with each other when you choose a different stream.

You can show or hide the hierarchical list:

### Picker with Stream Graph

With Picker, check the checkboxes for the streams you want to see, then click Apply to see those choices in the Stream Graph:

### Filter with Stream Graph

With Filter, the Stream Graph tab enables you to search for streams or restrict the streams that are displayed by using the Filter pane at the top of the tab. You can filter the streams by `Owner`, `Type`, `Root`, `Name`, `Parent`, and `Depot`.

If you have selected a stream, it is always in the view, whether you zoom out to see more streams, or zoom in to read details. You can also make the Width of streams be Small or Large:

You can show or hide the hierarchical list in the left pane.

Some streams might not match the filter result, but are shown because they are a parent of a stream that does match the filter result. These streams appear grayed out in the hierarchical list and colorless in the Stream Graph:

You can save a filter or apply a filter.

For more information about filters, see Search and filter.

## Context-menu Show in Stream Graph

To display the parents and children of any stream on the Streams or Stream Graph tab, click the stream, and in the context-menu choose Show in Stream Graph.

A new window displays the stream hierarchy for that stream, so you can compare the two views side-by-side.

## Tear off a view to compare side by side

To compare two views side by side, click the "Tear off this view" icon.

A new window opens, and you can reposition it.

## Stream Graph display conventions

The Stream Graph provides a graphical view of stream relationships and provides tools and shortcuts for working with streams.

If the dm.stream.parentview configurable is set to `1` or `2`, the `Copy/Merge Hints` filter can be set to show Files Only, Stream Spec Only, or Files and Stream Spec. Otherwise, the `Copy/Merge Hints` filter does not appear and hints are for Files Only.

The graph uses location and color to depict stream types: mainline streams are gray and placed in the middle of the graph, release streams are orange and appear above the mainline, and development streams are blue and appear below.

In the screenshot above,

- the grey band means that dev1 and dev22 have an `inherit` parent view
- blue band means rel1, dev2, and dev11 have a `noinherit` parent view.

Status hints between streams tell you which streams have changes to contribute and where the changes can be copied or merged:

Merge hint:

Copy hint:

The status hints are color-coded to indicate whether one or more integrations are pending between the stream and its parent:

- Gray: no merge or copy required
- Green: a merge or copy operation is available
  - Because dev11 and rel1 are `noinherit`, the changes to the parent stream are not automatically inherited. Therefore a merge is optional.
- Orange: stream must be updated, after which merge or copy is available

The workspace icon indicates the stream you are currently working in.

You can drag the workspace icon to another stream to switch your workspace to that stream. The Stream field value in the workspace definition changes to the new stream.

## Configure the stream graph display

1. In the Stream Graph tab, click the arrow icon at the top left to open the filter pane.

2. From the Depot list, select the depot that contains the streams you want to view.

3. If the depot contains more than one mainline stream, from the Mainline list, select the mainline stream you want displayed in the graph. The field below the list populates with a tree view of the selected stream.

   The full depot path appears at the bottom of the filter pane and at the top of the Stream Graph tab, next to the arrow icon.

4. (Optional) To focus on specific child streams, select them in the tree view.

   To view the streams you want to select, you might need to expand the tree. To access quick filter options, click the filter list .

   You can select multiple streams and then press the Spacebar to select or clear the respective check boxes.

5. Click Apply.

   The Stream Graph displays the streams that you specified.

6. To save the Stream graph:

   1. Click the filter list and select Save Graph As.

   2. In the Add Stream Graph Filter dialog box, enter a name for the filter and click OK.

      You can now access the filter from the filter list .

7. To close the filter pane, click the arrow icon again.

8. (Optional) To view the actual depot location of the selected streams in the Stream Graph, from the Label list, select Stream Root.

   The full depot path appears in the stream node for each stream:

   This is useful if you have parent streams with child task streams that are located in other depots.

9. (Optional) To change the size of the stream node to accommodate long depot paths, move the Width slider.

10. (Optional) Click the navigator icon to open the Graph Navigator.

    The Graph Navigator allows you to navigate the Stream graph when it is too big to fit into the available display area. In the Graph Navigator window, the red rectangle indicates the portion of the graph that is currently displayed in the Stream graph. You can use your mouse or cursor keys to move the rectangle and shift focus in the Stream graph.

    The navigator icon is only available if the Stream graph is larger than the display area.

## Display stream status

Double-click a stream to view a popup that contains status details:

## Work in a stream

To work in a stream or switch from one stream to another, do one of the following:

- In the Streams tab or the Stream Graph, right-click a stream and select Work in this Stream.

- In the Stream Graph, drag the Workspace icon from your current stream to the one you want to work in.

If your stream preferences are set to use a different workspace and to show an information dialog when switching workspaces, P4V prompts you to switch workspaces or create a new workspace. In this case, click the Create New Workspace button (if you have only one workspace), Switch Workspaces button (if you have two workspaces), or the Select Workspaces button (if you have more than two workspaces) to switch your workspace. If more than one workspace is associated with the stream, the Select Workspace dialog opens, where you can search for and select the workspace you want.

If your preferences are set to use the same workspace when you switch between streams, the workspace view changes to include the stream you are switching to. In other words, the Stream field value in the workspace definition changes to the new stream. When you do this and your Helix Core Server version is 2019.1 or later, then if you have files checked out to:

- The default changelist: P4V shelves them automatically in a numbered changelist with the description "Switched branch shelf" and unshelves them again to the default changelist when you switch back to that stream. However, note that the numbered changelist created for the interim shelf does not get deleted and remains in the system.
- A numbered changelist:P4V prompts you to shelve those files before switching. When you switch back to that stream, those files remain shelved in the numbered changelist. You have to unshelve them manually.

### Unrelated streams versus related streams

You can switch from any stream to any stream, and your work-in-progress will always be available when you switch back. This is true whether the streams are related or not, and whether they are in the same depot or not.

Two streams are:

- related if they share a direct or indirect relationship to the same mainline stream

- unrelated if they do not share a direct or indirect relationship to the same mainline stream

In the diagram above, `Mainline` and `MainShared` are unrelated streams in the same depot.

The four possible scenarios are that you switch to a:

- related stream in the same depot, such as from `patch 1.1` to `Rel 2.0`

- related stream in a different depot, such as from a task stream to a parent in a different depot

- unrelated stream in the same depot, such as from `DevNoBin` to `Server_dev`

- unrelated stream in a different depot
