Firstly welcome to the forum, have you checked the FAQ (I suggest you do it is full of helpful information).
With regards to your issue, what have you tried? Have you attempted any examples with using the MSChart component? If not, I would suggest you have a look for, and try, some as they will give you an insight on how to use the component.
Once you've got a handle at using it, see if you can alter one of the examples to use a datagrid as it's data source.
With a very quick bit of Google-ing I found this forum thread on the Social MSDN site which looks like they are doing the same thing you are.

Always try and do some research first before posting questions on here, especially if it something that has probably been done 1000+ times before, and you have not tried to solve the issue first.
Hope that helps.
