The ArrayDebugView-Add-In extends Visual Studio and adds graphical view capabilities to the debugger. You can plot the data from any array by specifying a pointer expression and a length. Features: Zoom-function, a cursor, saving to a file.
Good ol' ArrayDebugView. I've been using this one off and on since the VC6 days. Follow the instructions for VC2008 installation, and it will work just fine with VS2010 Professional.
This is a great add-in for the Visual Studio debugger to graph data in arrays. It's simple, it works and it's free.
