The GraphView elements can also have attributes using the same system as nodes and egdes. The data can be accessed through the Graph.

Arrows now look like in Overview. The API also now offers better customization through a central property system and is optimized for external applications as well. The API is also now considered as stable. The interface extends Statistics and implement the calculation of metrics over time. Important changes in graph events breaking API compatibility. Users may simply test if arrays returned by addedNodes , addedEdges , removedNodes and removedEdges are null before using them.

Add new executeLayout numIterations method in LayoutController. The StatisticsController now supports synchronous algorithm execution through the execute Statistics method. The model also allows to retrieve the ranking used in the auto transformation. An additional refreshRanking method has been added in the RankingBuilder SPI for a smoother auto transformation support.

This is a type of manipulator that defines and strategy for merging values of a row node or edge for an specific column. Instead of getNodeRanking and getEdgeRanking in the model, we introduce the concept of element type and generalize methods to it.

Use Ranking. Same idea for transformers, which are now defined by a unique name. Default transformers' name can be found in the Transformer interface. A RankingEvent has also been created. API users have to update to their client code to be compatible. Add a new interface nodes and edges share: Attributable. That allows to manipulate objects with attributes regardless if the object is a node or an edge.

Node, Edge, NodeData and EdgeData now implements this interface, and a getAttributes method has been added to Node and Edge to make development easier. Reason: this is not a metric but a fit on a model. The produced chart is not sufficient to link building service determine if data fits the model correctly.

Backward compatibility can't be assured, modules have to use switch to StAX. Added support of shortcut keys, availability of items and sub-items creation to Data Laboratory context menu actions NodesManipulator and EdgesManipulator. Add removeMetaEdge Edge to manually remove meta edges.

Add getTotalEdgeCount method to globally count the number of edges, regardless if the edge is proper or meta. Add methods in Graph API to better combine edges and meta edges features. Can only be imported from GEXF for now. Add 'destroy Filter filter ' in 'FilterBuilder' to receive notification when a filter query is removed and clean-up. Add 'GraphSettings. Modify 'StatisticsModel' to store reports directly instead of 'Statistics' instance. As a consequence, the model has now a 'getReport ' and a 'getResult ' method that UI can use.

The currently running statistics can now be get with a new 'getRunning ' method. Simplify and improve attribute events management. Event listeners now subscribe directly from the 'AttributeModel' instead of 'AttributeTable' and will receive events for all tables. Changes in Processor SPI. The 'Processor' has now setters instead of a 'process ' method with parameters. How processors are created remains the same. Creation of a 'ProcessorUI' interface for processors settings configuration.

A 'ProcessorUI' implementation provides a panel, which is shown when the import report is closing. The 'ProcessorUI' also allows to disable a processor with some conditions. Define the "Overview, "Data Laboratory" and "Preview" as perspectives. Create a new SPI for perspecives and perspective members. Members are simply the 'TopComponent' that belong to a perspective.

Plugins can implement 'PerspectiveMember' to define the open and close behaviour. All native types has now a related list type, except dynamic types. The list types inherits from 'AbstractList'. Changes in the way Import API deals with time intervals and dynamic data. For improving data cleanup possibilities, 'NodeDraftGetter' and 'EdgeDraftgetter' now returns an 'AttributeRow' instead of a list of attribute values only.

Finally to profit from latest improvements, draft elements returns directly a 'TimeInterval' type instead of the list of slices. Methods with 'Slice' have been renamed to 'Interval' for consistency reasons. Add dynamic types into Attributes API. Dynamic types store values with a time interval and query can be customized with estimators. A new 'GraphEventData' interface has been created to retrieve elements related to the events. The way exporters write data has been rationalized by using either 'java.

Writer' text or 'java. OutputStream' byte. The 'ExportController' has been improved to support all use-cases, including file, writer and stream export. Modifications have also be made to the 'ImportController' to support spigot import. The refactoring aim is to solve the singleton issue with importers and let users implement builders interface that create importers instance.

Mathieu Bastian became the software architect. Mac computer users had issues installing Gephi on their computers because of a Java compatibility issue. The codebase for the project is "mavenized", making the code more modular and easier to maintain. Visit the Gephi group on Facebook to get help,. The birth of Gephi The origin of Gephi lays in Web Atlas , a project started in involving Mathieu Jacomy , who was interested in the exploration of web-based graphs.

The latest Gephi version just got released, let us know what you think on Twitter or Facebook.
