It means that you are targeting a 64 bit platform, whereas the GraphicsGL is an assembly that can only be used in an application that is built as a 32 bit application. This means that when using the Chart, you must target a 32 bit platform.
Access the Configuration Manager (right click the solution in the Solution Explorer), and change the platform that is targeted.

It needs to be a x86 (32-bit) application. It will run on a x64 (64-bit) system. However, it needs to be targeted as a x86 application. For the moment, there no plan to upgrade it to support x64 applications. However, it is our only UI .NET component using unmanaged code. So, this is not an issue with our other UI .NET components.
