When I try to compile it I get the following error for Graph.cpp:
Undefined symbols:
"Graph::Coordinate::Coordinate(double)", referenced from:
Graph::Graph()…

We can use GDI+ to draw chart components in C# or VB.NET language in memory and once the components are drawn in memory, we can save the drawing in an image on the Web server. Once the image is saved, we can display this image in an ASP.NET page using any Image tag or image control.

Can anyone please tell me that once I've created a graph using Boost Graph library, how can I display that graph?
My biggest concern is that the edge weights are coming from an exernal data source over the network. And I need to be able to display the edgeweights live as they get updated.

I have an file that is a long list of weighted edges, in the following form
node1_id node2_id weight
node1_id node3_id weight
and so on. So one weighted edge per line.
I want to load this file into boost graph and find the connected components in the graph. Each of these connected components…

Hi all,
First, I should specify that my knowledge of statistics is fairly limited, so please forgive me if my question seems trivial or perhaps doesn't even make sense.
I have data that doesn't appear to be normally distributed. Typically, when I plot confidence intervals, I would use the mean…

Hi all, I'm trying to use boost::normal_distribution in order to generate a normal distribution with mean 0 and sigma 1.
The following code uses boost normal classes. Am I using them correctly?
#include <boost/random.hpp>
#include <boost/random/normal_distribution.hpp>
int main()

I'm math challenged today :(
I want to generate random numbers with a range (n to m, eg 100 to 150), but instead of purely random I want the results to be based on the normal distribution.
By this I mean that in general I want the numbers "clustered" around 125.
I've found this random number package…

Anyone know of a good implementation of this whose license is compatible with non-free iPhone apps?
As suggested in this question, Boost looks absolutely wonderful. But as best I can tell, it is only available in C++.
