function plot_thp_delay(a,id,Tlim,maxThp,maxDelay,maxC)
% This function plots the thorughput
% RTT and estimated queue delay
% Parameters:
%  a        : log file from SCReAM BW test tool
%             imported with the command
%             a = load(<logfile>);
%             where <logfile> is the name of the log file
%  id       : stream id
%  Tlim     : xmin and xmax limits [s], e.g. [0 100]
%  maxThp   : Max thorughput [Mbps]
%  maxDelay : Max delay [s]
%
% The script can be used with matlab or octave
