Create multiple subplot from one loop

Hi all,

I have 359 data set which can be used to create individual graphs, but that's too much. So i want to create 18 subplots where each have 20 graphs. The code i have, creates a subplot with the 1st 20 graphs and stops. I need it to carry on creating more subplots every 20 graphs until theres no more.

for j=2:length(xt); % xt 359x1 double
    subplot(5,4,j-1)
    plot(xs,yinternew(:,j)) % xs 17x1 double      yinternew 17x359 double
    xlabel('Strain, %')
    ylabel('H3H0 Torque')
    end 

Do you guys know how to do this?

Thank you for your help.

% some made-up data, for demonstration:
xs = 1:17;
yinternew = reshape(1:17*359,17,[]);

n_lines = 20; % 20 lines per subplot
n_total = size(yinternew,2); % n_total lines total

for j = 1:ceil(n_total/n_lines)
    subplot(5,4,j)
    idx = (j-1)*n_lines+2:j*n_lines+1;
    idx(idx > n_total) = [];
    plot(xs,yinternew(:,idx)) % xs 17x1 double      yinternew 17x359 double
    xlabel('Strain, %')
    ylabel('H3H0 Torque')
end

Consider the TiledLayout version instead of using subplot

% some made-up data, for demonstration:
xs = 1:17;
yinternew = reshape(1:17*359,17,[]);

n_lines = 20; % 20 lines per subplot
n_total = size(yinternew,2); % n_total lines total

tcl = tiledlayout(5,4,'TileSpacing','compact');
for j = 1:ceil(n_total/n_lines)
    nexttile()
    idx = (j-1)*n_lines+2:j*n_lines+1;
    idx(idx > n_total) = [];
    plot(xs,yinternew(:,idx)) % xs 17x1 double      yinternew 17x359 double
end
 xlabel(tcl,'Strain, %')
 ylabel(tcl,'H3H0 Torque')

Thank you for your answer.

But i think i may have used the wrong terms to explain what i wanted. So what i want is multiple figures, each figure should have 20 subplots (each plot have only 1 line - 1 data set). The figures should stop until there's no more data set.

So in total there should be 18 figures, each with 20 subplot and each subplot has only 1 line.

I hope this make better sense of what i want.

Thank you :)

These solutions address your question. You need to add a loop that produces the figures.

for i = 1:20
    figure()
    % <insert subplot or tiledlayout loop
end

% some made-up data, for demonstration:
xs = 1:17;
yinternew = reshape(1:17*359,17,[]);

n_lines = 20; % 20 subplots per figure, each with one line
n_total = size(yinternew,2)-1; % n_total lines total

for k = 1:ceil(n_total/n_lines)
    figure()
    tcl = tiledlayout(5,4,'TileSpacing','compact');
    xlabel(tcl,'Strain, %')
    ylabel(tcl,'H3H0 Torque')
    for j = 1:n_lines
        idx = (k-1)*n_lines+j+1;
        if idx > n_total+1
            break
        end
        nexttile(tcl);
        % subplot(5,4,j)
        plot(xs,yinternew(:,idx)) % xs 17x1 double      yinternew 17x359 double
        % xlabel('Strain, %')
        % ylabel('H3H0 Torque')
    end
end

Hi, thank you. I used all 3 of your suggestions and modified slighlty to make it work.
