Displaying and editing data by XY-plot

I have a mapping between 16 fixed numbers (points on the X axix) and their values (displayed on the Y axis). What I need is to display this data as XY-plot and to be able to change those values by moving selected point up or down. it should look someth开发者_如何学运维ing like:

What are possible approaches to implement this functionality (in winforms or wpf)? Maybe there are some third-party libraries which already implements most of it.

Also, there is a possible situation when fixed numbers contains two coordinates (placed in the square). In that case, a 3D-plot will be needed.
