问题 I want to visualize a Neo4j database in a graphical application. (I'm doing this primarily as a learning exercise). I want it to behave almost identically to the visualization in Neo4j's WebAdmin: When the graphic appears, I want to see the nodes moving around as they settle into their final locations, and I want the user to be able to click and drag node icons around the screen and have them stick where they are dropped, with the rest of the graph adjusting to account for the change. I have

问题 I am making a graph using NetworkX to export to visualize with Gephi. I've been adding various attributes to the nodes in my graph, without issue, until I tried adding colors. Does anyone know how to export a graph with "colored" nodes using networkx? (I've been writing into a gexf file, but don't care if it is another format as long as it is compatible with Gephi.) Here is the code in which I make the graph: def construct_weighted_graph(nodes, distance_dict, weighting_function, color = True)

问题 I have looked everywhere but I don't seem to able to get the answer for the latest version of Gephi (0.9.1). All I want to do is change the node size based on its in-degree for all the nodes on the graph. This used to be something I could do with the ranking tool but since this has been merged into the 'Appearance' tab I can't figure out how to do it. 回答1: Bit late but even if you have found it, it might help someone else. Check the highlighted areas 回答2: Weird but works: In Overview, in the

问题 I'm trying to create a normal graph and stream it to Gephi GUI using the Gephi toolkit. I am following the the toolkit and the streaming plugin tutorials. I am having difficulty getting my code to work because the lookup API is not returning valid values. On debug, I could find that both the Lookup methods below return null values because of which I am having trouble in accessing other methods using these objects. StreamingServer server = Lookup.getDefault().lookup(StreamingServer.class);

问题 I have a program which retrieves a list of PubMed publications and wish to build a graph of co-authorship, meaning that for each article I want to add each author (if not already present) as a vertex and add an undirected edge (or increase its weight) between every coauthor. I managed to write the first of the program which retrieves the list of authors for each publication and understand I could use the NetworkX library to build the graph (and then export it to GraphML for Gephi) but cannot

问题 I have created some links between agents (turtles) in NetLogo. This links will change at each time step. My aim is to export this data (i.e., turtles and links b/w them) to graph with vertices (turtles) edges (links), which can be given as input to Gephi. Is it possible to see the changes which occurs in netlogo in the graph when it is linked with Gephi. Can someone help me out. Thanks. 回答1: To export your network data in a format usable by Gephi, I would suggest using the nw:save-graphml

问题 I am trying to connect to gephi(0.9.1) through gremlin console. I have a graph in my titan database. I also have the streaming server enabled in my gephi. And through gremlin i executed the following commands: :plugin use tinkerpop.gephi g = TinkerFactory.createModern() :remote connect tinkerpop.gephi All these worked fine.But when i ran the last command: :> g I got the following error: ==>tinkergraph[vertices:6 edges:6] 16:07:16.783 [main] DEBUG groovyx.net.http.HTTPBuilder - POST http:/

问题 I have graph in Spark collected from different data sources. Is there simple way to export Spark GraphX graph to Gephi for visualization using scala? Any common data formats? 回答1: As far as I am concerned the only way you can export graph directly is to use some variation of CSV. All other formats supported by Gephi cannot be easily written in parallel. Problem with using basic CSV is that it doesn't support attributes. Since amount of data you can visualize using Gephi is rather limited a

问题 I have very few knowledges in java so I maybe misunderstood my problem: I'm working on the Gephi API which is in Java, and I used IKVMC to work on a dll. I tried to create an empty graph as explained here in the Gephi doc https://github.com/gephi/gephi/wiki/How-to-manipulate-Graph In C# I tried this: ProjectController pc; pc = (ProjectController)org.openide.util.Lookup.getDefault().lookup(typeof(ProjectController)); At the second line I get the following error: Exception non gérée : System

问题 I am quite new to Gephi, but after reading the tutorials on the official page I manged to make a decent graph. However, after adding few more nodes and edges to the database (currently has 31 nodes and 45 edges -see below) and re-generating the graph from layout tab, the graph disappeared and the "Force Atlas" distribution won't stop loading. I tried with other layout distributions with same results and I also tried with the zoom to extents icon but nothing would show up. Can anyone tell me
