subplot and surfc using graphic handle

Dear all:

I would like to make a figure of 4 x 2 subplots, I had the following code:

   surf_check = figure('Name','Likelihood Region','PaperType','A4',...
        'PaperOrientation','landscape','units','normalized',...
        'outerposition',[0 0.05 1 0.95]);
    subplot(4,2,1)
    minlb = [0.4;450];
    maxub = [0.8;500];
    surf1 = plot_surf_check('theta', 'var_eps_r', param_est,minlb,maxub,...
        param_fix,kalman_init,VarObs,index);
    subplot(4,2,2)
    minlb = [0.4;450];
    maxub = [0.9;500];
    surf2 = plot_surf_check('alpha', 'var_eps_r', param_est,minlb,maxub,...
        param_fix,kalman_init,VarObs,index);
    subplot(4,2,3)
    minlb = [0.97;450];
    maxub = [0.999;500];
    surf3 = plot_surf_check('beta', 'var_eps_r', param_est,minlb,maxub,...
        param_fix,kalman_init,VarObs,index);
    subplot(4,2,4)
    minlb = [0.5;450];
    maxub = [0.7;500];
    surf4 = plot_surf_check('sigma_L', 'var_eps_r', param_est,minlb,maxub,...
        param_fix,kalman_init,VarObs,index);
    subplot(4,2,5)
    minlb = [0.7;450];
    maxub = [0.98;500];
    surf5 = plot_surf_check('rho_a', 'var_eps_r', param_est,minlb,maxub,...
        param_fix,kalman_init,VarObs,index);
    subplot(4,2,6)
    minlb = [2;450];
    maxub = [2.5;500];
    surf6 = plot_surf_check('kappa_y', 'var_eps_r', param_est,minlb,maxub,...
        param_fix,kalman_init,VarObs,index);
    subplot(4,2,7)
    minlb = [0.01;450];
    maxub = [0.1;500];
    surf7 = plot_surf_check('kappa_pi', 'var_eps_r', param_est,minlb,maxub,...
        param_fix,kalman_init,VarObs,index);
    subplot(4,2,8)
    minlb = [2;450];
    maxub = [4.8;500];
    surf8 = plot_surf_check('var_eps_a', 'var_eps_r', param_est,minlb,maxub,...
        param_fix,kalman_init,VarObs,index);

Where plot_surf_check is a function does surfc by taking model parameters. The function returns a graphic handle.

My problem is, when I run the code, it gives me 8 figures, each one has only one plot on the corresponding subplot position without any graphics in it. I may miss something apparent here, any comments or help is much appreciated.

Cheers

Ben

I solve the problem. The issue was in plot_surf_check, there is a figure command triggers a new figure each time I run the code, by simply deleting it, I can create the subplot I want.
