My source material basically consists of a list of organizations and their members: Organization 1 Individual 1 Individual 2 Individual 3 Individual 4 Organization 2 Individual 5 Individual 1 Individual 6 Individual 7 Sometimes an individual shows up in different organizations (i.e. Individual 1 in this example). Questions: 1) How should I convert this information into edges so that the relationship between

DGML: how to enable the 'Go To Definition' for custom diagrams?

问题 I am generating a custom workflow diagram via DGML API where each node corresponds to a C# class. I would like to be able to use the built-in 'Go To Definition' feature but the documentation is lacking. 回答1: If you know the class´s filename and the position of the symbol definition, you can use the VsShellUtilities class to open the document and scroll the code artifact into the view (by setting the caret position). In one of my extensions I do something like this... If have a SourceInfo type

问题 I use jgraph ver. 5.14.0.0. ( http://www.jgraph.com ) When I try to apply layout to a jgraph, but for some weird reason it does not work. public static void layout(JGraph graph) { JGraphFacade facade = new JGraphFacade(graph); JGraphSimpleLayout lay = new JGraphSimpleLayout(JGraphSimpleLayout.TYPE_RANDOM, 100, 100); lay.run(facade); } I run this code to layout a graph, but cells does not move. I have not found tag for jgraph library. 回答1: Based on http://anonsvn.jboss.org/repos/jbossas

问题 I have several XML files which have a similar structure but with some differences that I cannot overlook. They are all TEI documents. I am looking for a way to outline the main structure. Take the following text as an example: <text xmlns="http://www.tei-c.org/ns/1.0" xml:id="d1"> <body xml:id="d2"> <div1 type="book" xml:id="d3"> <head>Songs of Innocence</head> <pb n="4"/> <div2 type="poem" xml:id="d4"> <head>Introduction</head> <lg type="stanza"> <l>Piping down the valleys wild, </l> <l

Tree visualization library - the one that calculates all node and line coordinates for given tree data

阅读更多关于 Tree visualization library - the one that calculates all node and line coordinates for given tree data

问题 (Visual) C++ world. I have a tree structure, want to visualize it. More specifically: I have a tree data. I want the library that processes this data and computes coordinates (in any logical coordinate space, say 2000x2000 logical pixels) for each nodes, AND for each lines connecting them. Line connecting the two nodes might not be a simple straight line, it might be curve or some sort of path consisting of straight line segments. Ideally I'd like the line defining path to be calculated for

Circular layout in VivaGraphJS

阅读更多关于 Circular layout in VivaGraphJS

I'm using VivaGraphJS to create my graph which is dynamic and keeps on updating as he data comes in. The problem is that VivaGraph doesn't have the circular layout by default which I need. I came across the circular layout in cytoscape.js which I'd like to port to VivaGraph. I'm not able to completely understand what changes to make so as to have a port to VivaGraph. It'll be really appreciated if you could help me and guide me through it. Thanks :) Also, here's an algorithm that I need since the number of crosses don't matter to me. function CircularLayout(width, height) { this.width = width;

Graph visualization libraries for SWT/AWT

阅读更多关于 Graph visualization libraries for SWT/AWT

问题 Is there a mature, solid open-source graph visualization library implementation for SWT or AWT (I am referring to sets of vertices connected with edges, not charts and diagrams)? Which one do you use/recommend? I saw Zest for SWT, but could not find a Maven repository for it. Thank you. 回答1: I recommend Prefuse: http://prefuse.org/ 回答2: Have a look at JUNG ( http://jung.sourceforge.net/ ) 回答3: If you don't want to use Zest (which I prefer), there is still Draw2D : Draw2D Also, there is a good

Node-based data visualization library in c or objective c

阅读更多关于 Node-based data visualization library in c or objective c

问题 I'm looking for a library in c or objective c that does node-data visualizations similar to http://arborjs.org/ helpful answers include, what are graphs like that called? names of libraries that do something like that. suggestions for implementation. I'm targeting iOS and/or MacOS, hence c or objective-c/cocoa. On iOS the javascript version runs super slow. Thanks! Edit: GraphViz looks great. I'm a little concerned it may have dependencies that are GPL, and thus can't be used on iOS...
