function  nt= plot6c(t,c,i)

% The function PLOT6C plots 6 subplots starting from the I-th component
% of the data c(n,k), where n is the number of data points and
% k is the number of IMF components.
% The number of subplots in vertical direction is equal to 6.
% X-axis range is defined as [min(t(1),t(tn)),max(t(1),t(tn))].
% The image on the screen closes all existing figures.
%
% Calling sequence-
% nt=plot6c(t,c,i)
%
% Input-
%	t		    - vector t(n) representing the 
%				time scale values
%	c		    - component data array c(n,k)
%	i		    - index of the first plotted component 
% Output-
%	nt		    - the handle of the figure
