def disp(name=None, idx=None):
    """displays selected data from (files written by) the class
    `CMADataLogger`.

    The call ``cma.disp(name, idx)`` is a shortcut for
    ``cma.CMADataLogger(name).disp(idx)``.

    Arguments
    ---------
    `name`
        name of the logger, filename prefix, `None` evaluates to
        the default ``'outcmaes'``
    `idx`
        indices corresponding to rows in the data file; by
        default the first five, then every 100-th, and the last
        10 rows. Too large index values are removed.

    The best ever observed iteration is also printed by default.

    Examples
    --------
    ::

       import cma
       from numpy import r_
       # assume some data are available from previous runs
       cma.disp(None, r_[0, -1])  # first and last
       cma.disp(None, r_[0:int(1e9):100, -1]) # every 100-th and last
       cma.disp(idx=r_[0, -10:0]) # first and ten last
       cma.disp(idx=r_[0:int(1e9):1000, -10:0])

    return CMADataLogger(name if name else CMADataLogger.default_prefix
                         ).disp(idx)
