A glitch with Edge label offset

阅读更多关于 A glitch with Edge label offset

问题 I have peculiar problem when I tried to offset the edge label in my Jung2 network. As shown in figure below the label causes the self loop difficult to see. So I decided to offset the label: vv.getRenderContext().setLabelOffset(20); And the Effect: Offset is effective for all the edges except for the edge that I need: the self loop. Anyone has a solution or a workaround ? EDIT: Does anyone know what the EdgeLabelClosenessTransformer does? And how to use it? This may solve my problem. vv

Vertex label color in Jung visualization

阅读更多关于 Vertex label color in Jung visualization

问题 I've created a graph with Jung and I'm looking into visualization options. I'm trying to change the color of the vertex labels, don't care if they are picked/unpicked, just from the get-go. I.e. I want to paint the vertex labels white, leave edge labels black (default). Can't seem to find a sample that works, the DefaultVertexLabelRenderer class should help I guess but I can't seem to get it to work. Any ideas? The code currently looks like this: public static void main(String[] args) { Graph

阅读更多关于 Jung: Add legends to the frame

问题 I need to add legends to my frame to show the meaning of different colored links and nodes. Does Jung have some in built legend functionality? Or do I need make my own by adding an extra panel to the right. 回答1: I added the legends in a simple way. First made an Image of the legends and then stick it to the panel via the JLabel. JLabel label = new JLabel(); label.setOpaque(true); label.setBackground(Color.WHITE); ImageIcon icon = new ImageIcon("Legend/SyncLegend.png"); label.setIcon(icon); vv

问题 I have created a network which consists of number of vertexes and edges. How do I show a popup message over a vertex when I move the mouse to that vertex? 回答1: AbstractPopupGraphMousePlugin and its subclasses are what you want: http://jung.sourceforge.net/doc/api/edu/uci/ics/jung/visualization/control/AbstractPopupGraphMousePlugin.html Look for its use in PluggableRendererDemo and in GraphEditorDemo. (Other samples also use it; those samples show how to create subclasses.) 来源： https:/

问题 I am impelementing an interface by JUNG library for moving agents (that are JUNG nodes) between nodes. When I command the agent to move from node 1 to node 2 , and before the agent's trip to node 2 has finished I command the agent to move to node 1 . I want the agent to move to node 1 after reaching node 2 But Instead the agent gets slowed down ( Because the new command decreases its speed) and when reaches node 2 by that decreased speed it returns to node 1 by the same decreased speed.
