\title{ Individual Phase I Hotelling Control Chart. }
\description{
  Builds the individual phase I Hotelling control chart.
}
\usage{
graphindI(T2, m, p)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{T2}{ The values of the T2 statistic. Shoul be a matrix. }
  \item{m}{ The number of samples generated previously in function dataindI. }
  \item{p}{ The dimension used previously in function dataindI. }
}
\value{
  Return a control chart.
}
\details{
  It builds the Hotelling T2 control chart for multivariate normal data (individual observations : m samples of size n=1) used in retrospective / validation analysis (phase I) ; the control limits are based on a beta distribution, and the covariance matrix estimator is based on the sucessive difference method.
