% eegplotold() - display data in a horizontal scrolling fashion
% with (optional) gui controls (version 2.3)
% Usage:
% >> eegplotold(data,srate,spacing,eloc_file,windowlength,title)
% >> eegplotold('noui',data,srate,spacing,eloc_file,startpoint,color)
%
% Inputs:
% data - Input data matrix (chans,timepoints)
% srate - Sampling rate in Hz {default|0: 256 Hz}
% spacing - Space between channels (default|0: max(data)-min(data))
% eloc_file - Electrode filename as in >> topoplot example
% [] -> no labels; default|0 -> integers 1:nchans
% vector of integers -> channel numbers
% windowlength - Number of seconds of EEG displayed {default 10 s}
% color - EEG plot color {default black/white}
% 'noui' - Display eeg in current axes without user controls
