Cannot find namespace System.Web.UI.DataVisualization.Charting

I'm wanting to use the inbuilt charting thats with .net 4. I have an existing MVC3 application, but I cannot seem to see the reference for this 开发者_JAVA百科namespace?

Anybody know where it is?

Thanks,

Darren.

I believe it's in the System.Web.DataVisualization DLL.

Add System.Web.UI.DataVisualization as Assembly reference to your project.

And after you will be able to declare the namespace:

using System.Web.UI.DataVisualization.Charting;

Add System.Web.DataVisualization as Assembly reference. (Was located in the .net Tab.) Add the following using statement

using Charting = System.Web.UI.DataVisualization.Charting;

From there you will reference your charting pieces like so

Charting.Chart myNewChart = new Charting.Chart();

It will help keep your namespace a bit cleaner and probably avoid some collisions as the lexicon surrounding the graphing world is not very unique.
