You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ft_multiplotER.m
    path of file: ./repos/fieldtrip
    
    the code of the file until where you have to start completion: function [cfg] = ft_multiplotER(cfg, varargin)

% FT_MULTIPLOTER plots the event-related potentials or event-related fields
% versus time, or the oscillatory activity (power or coherence) versus frequency.
% Multiple datasets can be overlayed. The plots are arranged according to
% the location of the channels specified in the layout.
%
% Use as
%   ft_multiplotER(cfg, data)
% or
%   ft_multiplotER(cfg, data, data2, ..
    
function does not apply a baseline correction again
  cfg.dataname = info.(ident).dataname;   % put data name in here, this cannot be resolved by other means
  cfg.channel = 'all';                    % make sure the topo displays all channels, not just the ones in this singleplot
  cfg.trials = 'all';                     % trial selection has already been taken care of
  cfg.comment = 'auto';
  cfg.xlim = range(1:2);
  % if user specified a ylim, copy it over to the zlim of topoplot
  if isfield(cfg, 'ylim')
    cfg.zlim = cfg.ylim;
    cfg = rmfield(cfg, 'ylim');
