Working with diagrams

1. Press Space.

2. In the search field that opens, start typing a name of the class you want to add. Then, select the desired class from the suggestion list.

   If you want to add a class that is out of the project scope, select the Include non-project items checkbox.

   Alternatively, select one or more elements in the Project tool window and drag them to the diagram.

1. In the diagram editor, select a node element you want to delete.

2. Right-click the element and from the context menu, select Delete Delete.

   Alternatively, select Refactor | Safe Delete AltDelete. In this case, PhpStorm checks for usages before applying the changes.

tip

You can quickly search for usages by pressing AltF7 on a code element.

You can perform some forward engineering while in the diagram editor.

1. In the diagram editor, select a class to which you want to add a new member and from the context menu, select New or press AltInsert. Then select a code element (a field or a method) you want to create.

2. Depending on your selection, PhpStorm opens the appropriate dialog where you specify the necessary information for creating the new element.

PhpStorm adds the item to your diagram and updates the source code accordingly.

You can view implementations and parent classes in your diagram. If PhpStorm finds more than one parent class or implementation, it displays a list of appropriate items. Select the one you need to see the connections between the parent and its children.

1. In the diagram editor, select an item for which you want to see implementations or parent classes.

2. Right-click the items and from the context menu, select the Show Implementations CtrlAlt0B or Show Parents CtrlAlt0P respectively.

3. In the popup that opens, select items you need and press Enter. To extend your selection up or down while in the popup, press Shift+Up or Shift+Down respectively.

You can configure the diagram settings so that you have certain options available by default when you create a diagram.

1. Press CtrlAlt0S to open the IDE settings and then select Tools | Diagrams.

2. In the right-hand pane, select the options that you want to see by default and click OK to apply your changes.

Most of the time, generated diagrams are big and complicated. Typically, you want to concentrate only on the specific part of the diagram. PhpStorm lets you filter paths between two diagram elements.

1. In the diagram editor, select two nodes on which you want to focus and right-click one of them to open the context menu.

2. From the context menu, select Analyze Graph | Focus On Paths Between Two Nodes.

   note

   If you want to focus not only on just two nodes, but on how the selected node is connected with its neighbors, select the Focus on Node Neighborhood option from the context menu.

3. In the dialog that opens, select additional options if needed and click Find.

   

   PhpStorm displays connections associated only with the selected nodes.

You can use this action to identify the important nodes in the graph.

1. In the diagram editor, right-click anywhere in the editor to open the context menu.

2. From the context menu, select Analyze Graph | Measure Centrality.

3. In the dialog that opens, select additional options if needed and click Measure.

   

   The node "importance" is expressed via fractional value from 0.0 to 1.0 measurement, and the brightest node selection should be explored first.
