Where I can find the display algorithm for multi-parents linking. I like to draw it on 2-dimension paper without crossing lines. So it is connecting with Set of parents to set of children where there is many to many relationship. ...
Hi All I want to plot some data in 3D in VC++. I searched the internet and MSDN for not much help. In SO, I found many links towards gnu, and things like that, which are (not) windows stuff. If possible, can someone point me to some 3d plot API, or source for VC++ ... Thank you ...
I have an svm in R and I would now like to plot the classificaiton space for this machine. I have found some examples on the Internet, but I can't seem to make sense of them. My R script is as follows: library(e1071) day_of_week <- c(0,1,2,3,4,5,6) holiday <- factor( c(T, F, F, F, F, F, T) ) model <- svm(day_of_week, holiday) plot(mode...
I need to sort some products base on user ratings. Suppose we have 3 products {a,b,c} and we have user's feed backs about this products. It's not important which user give us feed back (this question is not about correlative filtering if you are familiar with it - user interests is not the case here) Each of these below lines are feed...
This is the problem: I have n points (p1, p2, p3, .. pn), each of them can connect to any other with a determined cost x. Each point belongs to one of a set of point-types (for example "A" "B" "C" "D"...). The input of the method is the path I want to follow, for example "A-B-C-A-D-B". The output is the shortest path connecting the p...
Does anyone know an algorithm for the following problem: Given a undirected connected graph find the number of ways in which 2 distinct edges can be cut such that the graph becomes disconnected. I think a part of the problem (which i know an algorithm for) is calculating the number of ways in which 1 line can be cut so that it becomes ...
Other than RATS, are there any other Perl security scanners? Possibly also any STATIC only perl code graph engine which has an ability to follow data-flow or otherwise tainted input? ...
i need to generate graphs and equations for a website. the webserver runs on IIS and windows. I was looking at mathplot but wasn't sure if it can be used in a web environment .net is preferred your help is appreciated ...
I'm looking for an elegant Python program that does a BFS traveral of a DAG: Node A is connected to B (A->B) if A "depends on" B (think of python package Foo "depending upon" Bar: Foo->Bar). In a graph of about 7000 such nodes, I want to sort all nodes such that for all possible (i, j) where 1>=i<j<=7000 .. depends(Ni, Nj) is False. d...
I'm elaborating over a problem which seems hard to me and I'm not expecting a simple solution, but maybe there are proven practices or further reading that might make this easier. I'm pretty sure that the general problem pops up in many applications (for example garbage collection or transactional databases). My application has a graph ...
I have a tree structure of interconnected nodes of various types. Each node keeps track of which nodes it is connected to. In this structure I need to find the longest unconnected chain or path of same type nodes. I've read up on graphs and breadth/depth first searches but these don't quite yield the results I need. (they'll find a chai...
I have x,y data coming in from a [coordinates1] database (GIS - but this could be any database). I have my application with it's own coordinate system, referencing THE SAME MAP. I have established that a linear relationship exists between coordinates1(x,y) and coordinates2(x,y) as I have subtracted two different coordinates1 and coordin...
Given a Rails application on the server, what is the best charting/graphing solution for displaying dynamic, database driven charts/graph on a web page such as those available in Google Analytics. An optimal solution would include components that can speak JSON back-and-forth with the Rails application via AJAX. Thanks! ...
I am attempting to create a clickable piechart in ASP.NET 2.0 with C# using version 7.1 of Infragistics' software. The chart appears as it should, but the function marked in the OnChartDataClicked event is not called. From the .aspx: <igchart:UltraChart ID="UltraChart1" runat="server" OnChartDataClicked="DataRegionClicked"> <...
As a summer project, I have decided to practice basic algorithms and learn Haskell at the same time, by implementing large chunks of CLRS in Haskell. Things are going pretty swimmingly, so far, but since I started graph algorithms, I've noticed a lack: test input and output! For example, I've implemented Floyd-Warshall's algorithm, and ...
Hi all. I'm very new to Silverlight and programming in general so help me out here. I want to plot a Silverlight line/area graph by getting it's coordinates from a database when the user enters some data. The graph will change its value (by pressing refresh on the browser) when the value in the database changes according to what the use...
What I need is a method to display a graph of data from a tab delimited file uploaded to a website. Once the file is uploaded the program will convert the data to a graph or the graph be generated locally and sent to website, but it needs to be automated and in realtime. Thanks, Antone ...
I need to check the connectedness of directional nodes in a list. It is basically questions with 2 to 7 answers each. The answer picked dictates the next question. Since these pairs will be manually captured, I need to check each possible path for looping back (not allowed) and dead ends (all routes must stop at the END node) Any pointer...
I am not a jmeter expert, but I understand it can display graphs and save the data in .xml files. Is there a way to have jmeter actually create JPG, GIF or PNG files (or whatever format that can be embedded in html?) Added later: I need a solution that works in a batch run ...
I'm making some pretty big graphs, and the whitespace in the border is taking up a lot of pixels that would be better used by data. It seems that the border grows as the graph grows. Here are the guts of my graphing code: import matplotlib from pylab import figure fig = figure() ax = fig.add_subplot(111...
