nodes

So I'm fairly new to Java and programming and I was wondering how to create a node class? So far I have: public class ItemInfoNode{ private ItemInfoNode next; private ItemInfoNode prev; private ItemInfo info; public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev){ info = info; next = next; prev = prev; } public void setInfo(ItemInfo info){ info = info; } public void setNext(ItemInfoNode node){ next = node; } public void setPrev(ItemInfoNode node){ prev = node; } public ItemInfo getInfo(){ return info; } public ItemInfoNode getNext(){ return next; } public ItemInfoNode getPrev

I am trying to create a graph with node labels printed outside of nodes. I am able to generate 'offset' as shown below that solve the purpose. However, Sometimes the labels overlaps with edges (Which is undesirable as there are lots of empty spaces around nodes where the corresponding labels can be printed). I need to label these nodes in such a way that the labels does not overlap any edge or at least try to minimize overlap as much as possible. import networkx as nx from networkx.utils import is_list_of_ints, flatten import matplotlib.pyplot as plt G=nx.Graph() G = nx.complete_graph(5)

Given an undirected graph in which each node has a Cartesian coordinate in space that has the general shape of a tree, is there an algorithm to convert the graph into a tree, and find the appropriate root node? Note that our definition of a "tree" requires that branches do not diverge from parent nodes at acute angles. See the example graphs below. How do we find the red node? collapsar here is a suggestion on how to solve your problem. prerequisites notation: g graph, g.v graph vertices v,w,z : individual vertices e : individual edge n : number of vertices any combination of an undirected

Is there a way to adjust the bubble size (or colour) of nodes in Neo4j in relation to a node property value? For example, if each node has a size: "xxx" property, how would I make each node scale to this size? Is there a similar way to adjust relation lines? I know both nodes and relations can be adjusted to different colours or sizes all at once, but I can't figure out how to do this based on their properties. I tried creating a custom GRASS file, but weird things happened. This is what I used: node { diameter: 50px; color: #A5ABB6; border-color: #9AA1AC; border-width: 2px; text-color

I have a graph that changes over time (normally, new nodes are added). I need to regenerate the graph several times, and want all of the nodes to stick where they have been. This partially works when using graphviz with the fdp -algorithm, setting the pin -flag and specifying the positions with the pos -argument. In most cases, this works pretty well. But especially when new nodes are added, the layout sometimes changes drastically - which I need to avoid. Is there an option to actually force these pinned positions? It could result in an ugly graph, that would be alright - but they just need

Hi i have got the following error but my node is up and in jenkins logs everything is ok but on some of my jobs which are going on the nodes i've got the following trouble 12:59:29 [EnvInject] - Loading node environment variables. 12:59:29 ERROR: SEVERE ERROR occurs 12:59:29 org.jenkinsci.lib.envinject.EnvInjectException: hudson.remoting.ChannelClosedException: channel is already closed 12:59:29 at org.jenkinsci.plugins.envinject.service.EnvironmentVariablesNodeLoader.gatherEnvironmentVariablesNode(EnvironmentVariablesNodeLoader.java:75) 12:59:29 at org.jenkinsci.plugins.envinject

I'm using arbor.js to create a graph. How do I create an onclick event for a node, or make a node link somewhere upon being clicked? The Arborjs.org homepage has nodes which link to external pages upon being clicked, how do I replicate this, or make the node call javascript function upon being clicked? My current node and edges listing is in this format: var data = { nodes:{ threadstarter:{'color':'red','shape':'dot','label':'Animals'}, reply1:{'color':'green','shape':'dot','label':'dog'}, reply2:{'color':'blue','shape':'dot','label':'cat'} }, edges:{ threadstarter:{ reply1:{}, reply2:{} } } }
