I want to plot the figure when the data is runned 10000 data ,and intergrate the four figure in one(about 8bit 10bit 12bit 14bit) .

when run 1 data , it's will be plot one figure but that's not my want . please help my code , thanks !

below is my code :

case 'JITTER & cs'
    cs        = linspace(2e-12 , 4e-12 , 10000)
    J         = linspace(0     , 5e-12 , 10000)
    i =2; B_var=8;
    while B_var < 15
        Delta_var = (A^2)/(2^B_var);
        
        QN = (Delta_var^2)/12;     
        JITTER  = ((A^2)*(Win^2)*(J.*J))/2;
        TN = k*T./cs;
        Noise_both = JITTER+TN;
        
        func = Psig./(QN+Noise_both);
        SNR = 10*log10(func);
        hold on;
        figure;
        plot(Noise_both,SNR);
        title('SNR vs JITTER&cs')
        B_var = 8+i;
    end

Try putting the figure command and the hold on commands before the while loop (and put the figure command before the hold on).

If you paste your code here -- instead of an image of your code -- it would be easier to help, because we could run your code without needing to retype it all.

So, my suggestion was to change your code to this:

case 'JITTER & cs'
    cs        = linspace(2e-12 , 4e-12 , 10000)
    J         = linspace(0     , 5e-12 , 10000)
    i =2; B_var=8;
    figure
    hold on
    while B_var < 15
        Delta_var = (A^2)/(2^B_var);
        
        QN = (Delta_var^2)/12;     
        JITTER  = ((A^2)*(Win^2)*(J.*J))/2;
        TN = k*T./cs;
        Noise_both = JITTER+TN;
        
        func = Psig./(QN+Noise_both);
        SNR = 10*log10(func);
        plot(Noise_both,SNR);
        title('SNR vs JITTER&cs')
        B_var = 8+i;
    end
