I am porting Delphi project to WPF. I was using SDL Delphi Component Suite from www.lohninger.com[^]
(Math pack & Gui Pack) for the engineering drawing graphs in Delphi.

Math Pack - http://www.lohninger.com/mathpack.html[^]
GUI Pack - http://www.lohninger.com/guipack.html[^]

Can anyone suggest similar libraries in WPF environment??
Any suggestions will be highly appreciated

Thanks in advance..

For GUI perhaps Telerik, don't know anything for the math part.
