Yes, from the event file, you should be able to get any differential cross-section that you want.
For many definition of "x" you can use Madanalysis5 to have an easy user interface for the creation of such plot.
(But other plotting code exists as well)

Cheers,

Olivier

Not at LO (i.e. madevent).
For FLO and FNLO, there yes it is possible (but you have to code the observable in fortran yourself)
