function plot_Tsg( hTsgGUI, hAxes, PlotNum, X, Y, QC, para, colVal, ...
                   lineType, markType, markSize )
%
% Function to plot TSG parameters
% The program can plot parameter of style SSPS or SSPS_ADJUSTED
% in that last case we need to extract the name of the parameter
%
% Input
% -----
% hTsgGUI ........ Handle to the user interface
% hAxes   ........ Handle to the graphic axes
% PlotNum ........ Plot Number (used for the TAG)
% X
% Y
% QC ............. QC array - If empty plot using  Color specification
% para
% colVal ..........[]       - Draw Para taking into account color QC code
%                  'k''b'... - Draw Para using Color code 
% lineType ....... Matlab type : 'none', '-', '--', ':', '-.'
% markType ....... Matlab type
% markSize ....... Integer
% Para ........... Parametre whose difference with TSG data is plot
%
