This article will explain in detail what is the use of the new ASP.NET 3.5 chart control, the editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Microsoft recently released a cool new ASP.NET server control, < asp:chart / >, which can be used for free in ASP.NET 3.5 to facilitate rich browser-based chart scenarios:

After installation, the < asp:chart / > control appears on the data page of the toolbox and can be easily declared on any ASP.NET page as a standard server control:

< asp:chart / > supports a variety of rich chart options, including pie (pie chart), area (region), range (range), point (point), circular (circle), accumulation (accumulation), data distribution (data distribution), ajax interactive (AJAX interaction), doughnut (doughnut chart) and so on. You can declare chart data statically in the declaration of the control, or you can populate it dynamically using data binding. At run time, the server control generates an image (such as a .PNG file) that is referenced in the client HTML of the page using the < img/ > element output by the < asp:chart/ > control. The server control supports the ability to cache chart pictures, as well as the ability to save to a hard disk for use in persistence scenarios. It does not require the installation of other server software and can be used on any standard ASP.NET web page.

To experience how to use the < asp:chart / > control, I recommend downloading the Microsoft Chart Control sample project. The project includes more than 200 sample ASP.NET pages that can be run locally. Just open the web project in VS 2008 and click "run" to see their actual display, and then you can open the .aspx source code for each example to see how it is implemented.

The following example (under Chart Types- > Line Charts- > 3D Line and Curve Charts, Chart Type-> Graph-> 3D Graph) demonstrates how to make Line, Spline, and StepLine charts:

The following example (under Chart Types- > Pie and Doughnut Charts, chart type-> pie chart and doughnut chart) demonstrates various pie and 3D doughnut chart options:

The following example (under Chart Types- > Advanced Financial Charts, Chart Type-> Advanced Financial Chart) demonstrates some curve charts:

This should provide your standard ASP.NET feature kit with a very useful (and free) tool that allows you to easily add richer visual effects and data flow scenarios to your ASP.NET application.
