I'm trying to create a graph using Graphviz (complied with neato), and I would like to place nodes in specific locations. For this, I'm specifying exact edge lengths for all edges. However, I don't want all edges to be visible in the final image. Do you know of any way to hide edges? I should mention that I tried coloring the edges whi...
What's the correct way to go about persisting a GWT Visualization API DataTable? Should I find a way to serialize the DataTable object or should I write the table cell by cell to a relational database? I'm trying to build a RIA using the GWT-MVP pattern described here http://blog.hivedevelopment.co.uk/2009/08/google-web-toolkit-gwt-mvp...
I'm creating a graph using Graphviz (compiled with neato). This graph contains many overlapping nodes which is perfectly fine. However, there is a group of large nodes which I prefer to always be on top of other small nodes - even-though I prefer to define the large nodes first in the graph (which makes them get painted at the very botto...
I have a graph to which I add and delete nodes (using animation with FunctionSequence) according to the user's interaction with the application. My problem is that as I add or remove more nodes, the drag sensibility of nodes increases. In other words when I drag a node after adding and removing nodes from the graph even a small movement ...
Can you help me to connect to my postgresql database with python? I need to create graphic interface with python which will visualize shapefile data from my database (i have about 50 polygons in shapefile format in that database). Can you help me with creating such application? I am begginer in python. ...
i have a database that lists a bunch of applications and their dependencies. Some dependencies also have other dependencies. I am trying to figure out a web based way to visualize this on a web page so you can see the whole list of recursive dependencies throughout the data. i am using asp.net mvc. any suggestions? ...
Are there any frameworks or open-source code that would simplify the process of implementing a real-time oscilloscope (time-domain audio visualisation) in OSX? Ideally, I want to display a simple animated view representing the audio signal being input by the microphone input. ...
I am using a C# implementation of Mersenne Twister I downloaded from CenterSpace. I have two problems with it: No matter how I seed the algorithm it does not pass DieHard tests, and by that I mean I get quite a lot of 1s and 0s for p-value. Also my KStest on 269 p-values is 0. Well, I cannot quite interpret p-value, but I think a few 1...
I just got into information-visualization and scientific-visualization and have been using Piccolo and a little with JFreeChart. I am trying to find a few new libraries that I can start using. I am looking specifically for libraries that involve multi-dimensional visualization and map overlaying (something like open-layers), but would be...
I am working on a simulation in Queueing Theory, within a wxPython GUI. (Project link.) What would be a good tool for visualizing the simulations? The visualization should consist of simple objects, such as clients, servers, a facility and a population. They should all be represented by simple boxes or something like that. There will be ...
I'm not sure how useful this would be, but I thought it might be neat to visualize the objects being used in my program and which objects are being referenced from where. I'm guessing it would generate some data that would be used by a program like graphviz. Are there any tools that do this, otherwise how hard would it be to do this myse...
I have some data. 224,000 rows of it, in a SQLite database. I want to extract time series information from it to feed a data visualisation tool. Essentially, each row in the db is an event that has (among other things not strictly relevant) a time-date group in seconds since the epoch and a name responsible for it. I want to extract how ...
Hi, I try to ask my question here because nobody on paraview mailing-list answered until now. I try to get a tiled display to work with ParaView, so here is my setup: I have 3 Windows XP machines each equiped with graphic cards. Each graphics card is connected to a monitor, so I want to get my ParaView output on that three monitors. I ...
I am trying to visualize a large multi-dimensional dataset. Each dimension has a different range. Values in one column may range between 0-100 while values in another could range from a few hundred thousand to a few hundred million. Therefore it is really hard to show a graph with a reasonable scale. I would like to visualize them using ...
I'd like to create to some custom visualization effects to a sound wave in Silverlight. As of Silverlight 3 there's the MediaElement class which does a great job in playing sounds/videos. To visualize however I would need some kind of event callback with some information on the currently played segment of the sound. Does the framework h...
VELODYNE'S HDL-64E is A HIGH DEFINITION LIDAR SENSOR FOR 3-D APPLICATIONS. I have a task of generating a surface from point data set.Is there any code just to visualize the point cloud , like the one shown here ...
My program is attempting to draw grammars in C# & WPF. I have: 1 DataStructure project which describes a tree structure of how it should be visualised. Each node in the tree relates to a symbol in the grammar. Nodes at the top define the rule for that nonterminal symbol. 1 Drawer project which describes the user controls in WPF. I nee...
Is there a way that I can make VTK have the Y axis go down (when increasing values) rather than up? I'd like my VTK windows to match my non-VTK windows in displaying data, which all have the Y axis going down. ...
Hi All, Warning, this is a sheer-laziness query! As my project develops, so also do the number of functions within a class. I also have a number of classes per .py file. So what I would like to do is re-sort them to that the function names are organised [sorry, UK here, I've already compromised hugely with the 'z' in Alphabetizing ;-)] ...
I'm going to program a fancy (animated) about-box for an app I'm working on. Since this is where programmers are often allowed to shine and play with code, I'm eager to find out what kind of cool algorithms the community has implemented. The algorithms can be animated fractals, sine blobs, flames, smoke, particle systems etc. However...
