JGraphT

问题 Running below code on an already constructed Graph (usind ArbEdge.class as Edges) Graph<String, ArbEdge> graph = new DefaultDirectedWeightedGraph<>(ArbEdge.class); public void pngGraph() { JGraphXAdapter<String, ArbEdge> graphAdapter = new JGraphXAdapter<String, ArbEdge>(this.getGraph()); mxIGraphLayout layout = new mxCircleLayout(graphAdapter); // mxParallelEdgeLayout layout = new mxParallelEdgeLayout(graphAdapter); layout.execute(graphAdapter.getDefaultParent()); BufferedImage image =

问题 I want to create a graph with subgraphs (I think cluster is a synonymous - not sure ?). Someone could explain how to create this type of graph and how to export this composite graph. I readed this post Creating graph with clusters using jgrapht but i am not sure to understand this sentence "You could create a graph where each vertex is a graph by itself; edges between these vertices represent relations between these special vertices .". Does it mean that in this case verticles are relations

问题 Is there any way to create a graph with clusters using jgrapht? Example graph with two clusters "process #1" and "process #2": Expected dot file content : digraph G { subgraph cluster_0 { style=filled; color=lightgrey; node [style=filled,color=white]; a0 -> a1 -> a2 -> a3; label = "process #1"; } subgraph cluster_1 { node [style=filled]; b0 -> b1 -> b2 -> b3; label = "process #2"; color=blue } start -> a0; start -> b0; a1 -> b3; b2 -> a3; a3 -> a0; a3 -> end; b3 -> end; start [shape=Mdiamond]

问题 I have very simple graph strict digraph G { <assembly-raw-file>; <dataset-processing>; <feature-processing-1>; <feature-processing-2>; <mh.permute-variables-and-hyper-params>; <mh.finish>; <assembly-raw-file> -> <dataset-processing>; <dataset-processing> -> <feature-processing-1>; <dataset-processing> -> <feature-processing-2>; <dataset-processing> -> <mh.permute-variables-and-hyper-params>; <feature-processing-1> -> <mh.permute-variables-and-hyper-params>; <feature-processing-2> -> <mh

问题 I try to show graphs in JGraphx. Everything is fine as long as I use directed Graphs, but when I try to show an undirected one, its shown with direction. The code is from the demo of jgrapht. package org.jgrapht.demo; import com.mxgraph.layout.*; import com.mxgraph.swing.*; import java.awt.*; import java.nio.file.FileSystem; import javax.swing.*; import org.jgrapht.*; import org.jgrapht.ext.*; import org.jgrapht.graph.*; /** * A demo applet that shows how to use JGraphX to visualize JGraphT

问题 What does dot class mean in the parameter passed to Constructor I am using jgrapht for the first time . I have this question What are we passing to the constructor of the DefaultDirectedGraph class? I mean what does DefaultEdge.class means ? There is no static field with that name inside that class. I mean what is actual being passed to the contructor of that class. What does the dot class mean there ? DirectedGraph<String, DefaultEdge> g = new DefaultDirectedGraph<String, DefaultEdge>

问题 I want to draw some graphs including vertices and edges in my application. I found that JGraph is a good library for plotting graphs. I went through some online sources about it but couldn't find any relevant articles about how to embed a JGraph in a Swing application. (Showing a JGraph in a JFrame etc). Can Any one help me with that? 回答1: This code worked for me: // Insert the cells via the cache, so they get selected graph.getGraphLayoutCache().insert(cells); // Show in Frame JFrame frame =
