"Are you looking for a way to draw in .Net? Here’s yet another charting class library with a high degree of configurability that is also easy to use.

ZedGraph is a set of classes, written in C#, for creating 2D line and bar graphs of arbitrary datasets. The classes provide a high degree of flexibility — almost every aspect of the graph can be user-modified. At the same time, usage of the classes is kept simple by providing default values for all of the graph attributes. The classes include code for choosing appropriate scale ranges and step sizes based on the range of data values being plotted.

ZedGraph also includes a UserControl interface, allowing drag and drop editing within the Visual Studio forms editor, plus access from other languages such as C++ and VB. ZedGraph is licensed under the LGPL."

There are quite a few AJAX demos and examples on the web right now. While these are invaluable to learning AJAX, some people need a bit more information than just a raw piece of code. In todays environment there are many ways to learn AJAX including, books, classes, conferences, workshops and tutorials. Of these the only one that is free and accessible to everyone are web-based tutorials. The following is a list of what I consider the be the best and most helpful AJAX tutorials that I’ve found over the past year.
