Microsoft ships MS Graph 7 with VFP6 and MS Chart with VFP7. They are ActiveX controls. When placing them on Form, from the context menu you can choose Help to see their documentation (its in Visual Basic, but helps a lot). Also there are Solutions Samples in VFP with Charting.

Note that there are some issues when deploying MS Graph App on machine without MS Office. MS Chart works fine.
