[Rasch - category probability]

BEANS

hi, I don't know where to ask about IRT and Rasch thing in here... so I just post it.

Question is 'how to do IRT plot in Jemerik].

I can make each item to category probability 'graph -> IRT plot',

but how to make each 'factor' category probability graph

sorry for posting like this, but if someone know how to do this things... please leave comments
