/set or Is/set types, such as GetName (0/setname (' HT ') and isexpanded (), for common attribute operations
attr type, accessed via getAttr (name) and setAttr (key, value), which is HT reserved for the user to store business data
Style type, operated by GetStyle (name) and SetStyle (key, value), Graphview meta style controlled by the Type property
Here I am adding the text description through the style type, setting the displayed text through the ' label ' property:EDGE.S ({//setst
In the network topology diagram, it is often necessary to use the automatic layout of the function, in the hierarchical relationship of big data, by hand a place is not too realistic, the workload is quite large, then there is the concept of automatic layout, to liberate the layout of the hands, so that the network topology map can lay out a beautiful pattern, Of
, the shortest total, length of wires so, the construction can is done very soon.InputThe input contains several test cases. Each test case is starts with a line containing the integer n (n ≤100) and the number of nodes in the destroy Ed Network, and m (m ≤104), the number of pairs of nodes between which a wire can be built. The next N lines each contain an ordered pair XI and Yi, giving the Cartesian coordinates of TH E nodes. Then follow M lines eac
connection information between the nodes, from and to two, which describes which node the edge is from and to which, and the last 3 columns are custom properties for each edgeOnce the two data frames have been created, you can create a graph with the Graph_from_data_frame function, with the following code:G The first parameter is the data frame that holds the edge information, the directed parameter controls whether the graph has direction, and the vertices parameter is the data frame that hold
Test instructionsTo a directed graph, ask him for the minimum spanning tree.Analysis:Directed graph of the fixed-point minimum spanning tree, also known as the minimum map, with the solution of the algorithm, the algorithm step-by detailed explanation:
First determine if there is a minimum tree diagram, from the root node Dfs again.
Root node, for all other vertex V, find a shortest edge with V as the end point.
Determine whether the
In the telecommunication network management system, the real-time display of the equipment status information is very important, usually mount a bunch of icons to display the status or alarm information, the limited information of the icons, sometimes need more detailed panels, even in the form of a chart, this article will combine the needs of recent customers, using the Qunee1.6 beta version, Realize real-time display of device information in topolo
A few days ago, just discussed this problem with a group of friends, he is the SNMP switch when the diagram is intermittent.I also have this case, but when monitoring Tomcat, Jstat consumes more than 90 CPU,Cause the normal monitoring project to break the diagram.In fact, it let us wait for the seconds, then the meaning constantly superimposed 15s, is not 5 minutes after not out of the picture,Or is the load high not out of the picture?CaseZabbix_serv
Definition: The smallest spanning tree on a graph.Algorithm process: The same as the minimum spanning tree, but this is not a graph, but it can also use a similar algorithm, the smallest tree diagram of the first algorithm number of Zhu Liu algorithm, based on the minimum number of spanning trees algorithm formation.We know that in the minimum spanning tree algorithm, we select the shortest length of the edge each time, if the conditions are satisfied

There is a network in the dormitory, and the matrix needs to be converted into a network map to make it look a little bit. So I wrote such a function here.
The function is to change the adjacent matrix or associated matrix into a network diagram, but I can only convert it to an undirected graph here. I still need to

drawing technique of double-code Network Diagram
1, first from the "work schedule" to find all the beginning of the operation (no close to the operation of the operation), draw a node, from the node to say there is a starting process.
2, find all the process of the tight after the process to find all the end of the process. Draw a node and introduce all the end operations to this node.
3, drawing close b
