Matt, I'm in the application process for Summer of Code 2007 and put together a rapid prototype of the concept. So while I've begun work on the idea, it's in its infancy. If you'd like to see the prototype code, I can post it to the Sandbox Vault or provide a link. However, since it's still in the design/redesign stages, feel free to make suggestions for features you'd like to see! Features I intend to add include labels of data points, smart drawing + labeling of axis intervals, the ability to include a least-squares regression with the data, ability to highlight or label min/max values. Right now it only supports vector<double>, which was used to iron out the interface, but will quickly be changed to support iterators for generic STL containers, much as <algorithm> functions do. As long as the user provides a pointer to a function to convert an object to a floating point value, they will be able to graph any container of any object. As a reference, the current prototype's capabilities are indicated in the following .svg file. This shows a graph of the functions f(x) = .5x and f(x) = x^2 graphed from -10<=x<=10. This is not the nicest "window" with which to view it, but it demonstrates that the user can change it at his/her whim. http://www.tcnj.edu/~voytko2/first.svg So you should not have to wait much past the summer for a working version of this program!

[mailto:boost-bounces@lists.boost.org] On Behalf Of Jake Voytko The C++/STL library does not provide a quick and easy way for a visualization of numerical data to occur, and neither does Boost. I propose writing a minimal SVG class that can write in the SVG (Scalable Vector Graphics) format along with helper functions to help users visualize data stored in arrays as well as common STL containers. There will also be a subclass, svg_graph, that acts as a user interface for the graph data. The user will be able to customize how they would like the graph to be styled, and the data to be displayed. Since the SVG format is recognized by all major browsers, these could easily be incorporated with Boost documentation in place of .jpg or .gif files.
Hi Jake,
That sounds really cool, in fact we could put something like that to use now. Are you just brain storming or have you begun work on something already?
Regards, Matt
