I would like to have some suggestions about which third-part controls can we use in our Visual C++ MFC application?
We've deployed IOComp's Plot Pack in both ActiveX and .Net flavors with great success. Great API, incredibly flexible, provides a toolbar that lets users pan/zoom/customize. It's solid, has a long track record, relatively inexpensive, and is very fast.
(I'm not affiliated, by the way.)
If you don't mind paying, there's FarPoint Spread:

Just for completeness Scientific charting control. I used it some time ago and it was pretty easy.

We have used the ActiveX version of TeeChart (http://www.steema.com/), which works nicely and comes with many MFC examples. It's ActiveX though, that may or may not be a problem in your case.
Best chart for MFC I have seen, modern, stable and very well written
