There are many asp.net components and controls out there, most of which cost more than 500$, especially the charting and graphing components that you can use to generate visually cool reports for your web application. I have been working on a similar project, need to generate graphical report, and searched for non-complex charting .NET components which i can use for free. There are such controls, the best for me is WebChart control.
WebControl for creating charts, that render as images(png, jpg, gif, etc). Supports:
- Line Charts
- Smooth Line Charts
- Column Charts
- Area Charts
- Scattered Charts
- Stacked Column Charts
- Pie Charts
- Stacked Area Charts
If you don't need to draw complex, over-cool, unusual reports, you can try Webchart for free. You can also find more useful tools for free, IIS 7 Reports, IIS 7 MRU Module, Code Translator, CodeColorizer, XGrid, X-Map Editor, ExcelXmlWriter, DbDiagrams, Forum Colorizer, UmlDiagrams and Drawing Board
Good luck.
