how to plot X or Kp against the number of generations on y axis ?

%initialize genetic
FitnessFcn = @PID_objfun_ITAE
LB=[4 2 ];UB=[50 80 ];
options = gaoptimset;
options=gaoptimset(options,'populationsize',30,'Generations',6,'SelectionFcn', @selectionroulette)
%options = gaoptimset(options,'InitialPop', final_pop); % to improve search
options = gaoptimset(options,'MutationFcn' ,{ @mutationuniform 0.001 });
options = gaoptimset(options,'CrossoverFcn',@crossoverarithmetic);
options = gaoptimset(options,'PopInitRange' ,[4 2 ;50 80 ]);% bounds for ITAE
%options = gaoptimset(options,'PopInitRange' ,[3 2 0;12 15 5]);%bounds for MSE
options = gaoptimset(options,'PlotFcns', { @gaplotbestf @gaplotbestindiv });

%start algorithm
fprintf('Genetic Algorithm values :KP = %7.5f;KI = %7.4f ',x(1),x(2) )
