\title{Plot an item's characteristic curves across frames}
\usage{
plot_icc_frames(fit, item, n_groups = fit$n_groups, grid = seq(-5, 5, 0.05))
}
\arguments{
\item{fit}{A fitted object from \code{\link{rasch_efrm}}.}

\item{item}{Underlying item name.}

\item{n_groups}{Number of class intervals for the observed means.}

\item{grid}{Logit grid.}
}
\value{
Called for its plotting side effect; invisibly \code{NULL}.
}
\description{
The signature display of the extended frame of reference model: the model
expected-score curve of one underlying item drawn once per person group
(curves fan with the group units), with observed class-interval means per
group overlaid.
