subgraph

问题 From this question it turned out that in some cases it might be desirable to align a subplot relative to another's plot axes coordinates. If you check the gnuplot documentation, you will find that labels, arrows, objects (rectangles, polygons, circles, ...) can be positioned in different coordinate systems, i.e. axes, graph and screen (see help coordinates ). Subplots in a multiplot environment, however, (as far as I know) can only be aligned and sized relative to the screen, see help origin

问题 I want to plot a portion of a graph according to a specific node and ideally a distance from that node or a number of nodes as part of the sub graph. The data.frame that I am graphing is as follows: Column 1 Column 2 Sequence A B 1 A D 2 D B 3 Z E 4 E D 5 this is the code: network <- graph.data.frame(data_to_graph[,c(1,2)]) subnetwork <- induced.subgraph(network, vids = 30, impl = 'copy_and_delete', eids = c(5,6,7,8,9,10,11,12,13,14,15)) plot(subnetwork) I would like, by specifying an element

问题 I have a graph with different clusters. Basically I want to pair different nodes i.e. show somehow that different nodes have special relationship. So I decided to use clusters so that the nodes appear in a rectangle. The problem is that a node can be in relationship with more than one node i.e. it could be in different clusters. But I have not found out a way to insert a node in two clusters. I have the following code: digraph G {rankdir="LR"; node [fontname = "font-awesome"]; subgraph

问题 I have a directed graph G in networkx and I want to get the minimum spanning tree of it. I do: T = nx.algorithms.minimum_spanning_tree( G.to_undirected() ) This is undirected and I would like to restore the directions but I don't know how to do it. I tried: G[T.edges()] This last line looks very pythonic but this is not the way networkx works, apparently... Does anyone knows how to do it? In other words: How can I get the subgraph of a directed tree given the (undirected) edges ? 回答1: You can

问题 I'm using Networkx to compute some measures of a graph such as diameter, clustering coefficient, etc. It's straight forward how to do this for graph as a whole. What I'm interested in is finding these measures between nodes that have same attribute(say color). I'm thinking if I could partition the graph into different sub graphs, where nodes in each sub graph are of the same color, then I could accomplish go ahead and measure diameter in this sub graph. So my question is: Is there a way to

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I'm going to start a scientific project about automata and graph theory, and I'm searching for a graph library that supports features like: directed/undirected graphs graph isomorphism test (i.e. is graph g1 isomorphic w.r.t. g2?) subgraph isomorphism test (i.e. is a graph g1 isomorphic to a subgraph of g2?)
