How can I create three 2,2,x subplots (total 12 subplots in 3 plots) from my surface of my FourierAnalysis?

How can I create three 2,2,x subplots (total 12 plots in 3 subplots) from my surface of my FourierAnalysis?

I want to do a FourierAnalysis of the following Frequencies:

fAnalysis = [20,25,30,35,40,45,55,65,75,85,105,130]; % Hz

Actually i get 12 single Plots when I compile:

%% spatial analysis
fAnalysisBin = round(fAnalysis/dF);

% Todo: iterate for all subwoofers
for iFreq = 1:length(fAnalysis)
    XFreq = X_tmp(fAnalysisBin(iFreq),:);
    XFreq = reshape(XFreq,nMic,nPos);

    % Todo: Subplots!
    figure
    surf(20*log10(abs(B)))

end

How can I plot the frequencies

20, 25, 30, 35 40, 45, 55, 65 75, 85, 105, 130

in a 2x2 subplot so I get 3 windows within 4 plots of the belongig frequencies?

When I try to subplot it, it gives me 12 windows within 3 empty plots and 1 frequencies

Thank you all for helping!

figure(1)
subplot(2,2,1);
% more subplot
figure(2);
subplot(2,2,2);
% more subplot
figure(3);
subplot(2,2,4)
% more subplot
