What algorithms are good for interactive/realtime graph-drawing for live data and direct-manipulation? Failing that - what libraries do you use to draw graphs? Suggestions; Prefuse information-visualization toolkit any others? BTW- I mean graphs in the graph-theory sense - points and lines any language by live I mean the graph...
we have an organization that has about 50 different software projects going on (about 90 developers). some big, some small. some are front to back solutions and some are building on top of existing solutions and technologies. some of these projects are new initiative and some are incremental improvements over existing software that we ...
Hello, so I want to write a matrix explorer which enables me to reorder rows and columns of a matrix. For this porpouse I used the Jtable class. Now the problem that I have is that it is very difficult to reorder a matrix by looking at double values, so I would like to print the matrix not with the double values but with circles in whic...
Hello, I am programming a Matrix Explorer that allows me to reorder the rows and columns of a matrix. The Problem that I have is that I want the drag and drop to be visually consistent, meaning that the rows reordering should be visually similar to the one of the columns reordering( that is already implemented in Jtable). In the Jtable...
Hi, I've been tasked with creating a simple Python web-based app to graphically represent the "differences" between various servers, in terms of the contents of various key config files throughout the filesystem. 1. High Level Heatmap For a high-level overview, I was thinking of creating a heatmap of each system (e.g. http://www.jjguy...
I have a tree based dataset that I want to visualize in my webpage. the data is just your basic tree: there is a parent node, with subnodes and then subnodes of those nodes. I am looking for a package to visualize the data in a tree format. does anyone know of one? Google has one, but Im wondering if there ar other alternatives ...
I'm writing a Log-Event correlator. The principle is to have several log-sources analyzing the same signal in multiple places, and then correlate all events to determine causes by method of least-common-denominator. The output becomes something like; (event-count can be expanded to actual events for drill-down) nodeA,nodeB,nodeC: 524 n...
I am extremely frustrated with trying to prune and hand over to Protovis a set of arrays only containing numbers from a set of data objects that looks something like below to draw up three separate pie charts (pv.Wedge) for each object... myData = [{dept:"Accounting",sal:90000,equ:10000,trvl:267,extra:5000}, {dept:"Sales",...
