Hi guys, I have bunch of excel files that almost everything in them is similar. All I want is creating a loop instead of coding 10 figures, that some data is loaded from row (I can get this part done), then using a tiled layout or subplot to click run and MATLAB loops and adds figures to the next tile but I cant get this going:

for r = 1:10
    X=xlsread(B) - for instance
     tiledlayout(2,5)
    scatter(X(the plot works))
    nexttile
end

在 MATLAB Online 中打开

for r = 1:10
    subplot(2,5,r)
    plot(randi(10,5,5),'ro')
end

If you have two loops, you can use as follows:

for r = 1:2
    for k=1:5
        subplot(2,5,(r-1)*5+k) % 5 is used because the maximum iteration of k is 5
        plot(randi(10,5,5),'ro')
    end
end

Thank you so much @ANKUR KUMAR. This is definitely working now. Just a quick question, could you please teach me why we should do it this way?

We need to use cat command to concatenate multiple separate matrices into a single matrix. The first argument in the cat command is the dimension along which you wish to concatenate.

> should a nexttile be in the loop?

Yes, but the tiled layout should be defined before the loop.

The first two examples listed in this answer show how to use tiledlayout in a loop with a global legend.

Here's another example.

fig = figure();

tlo = tiledlayout(2,3);

h = gobjects(1,6);

colors = lines(6);

for i = 1:6

ax = nexttile(tlo);

h(i) = plot(ax, 1:10, rand(1,10), 'Color', colors(i,:), 'DisplayName', sprintf('line %d',i));

end

lg = legend(h);

lg.Layout.Tile = 'East'; % <-- place legend east of tiles

Hey Adam, @Adam Danz

I saw your answer on this post:

https://www.mathworks.com/matlabcentral/answers/6881-legend-in-subplot

Could you please teach me how to corporate that in a for loop? should a nexttile be in the loop?

Thank you!

Hey Adam ! @Adam Danz

I have similar question;

How can we plot multiple figures with subplots using loop?

For example, using loops, MATLAB should generate 17 figures and allocate 10 subplots in each figure.

Figure should have 1 to 10 subplots then figure two should have 11 to 20 and so on.

There are 170 samples. Any idea how it can be done ?

I would appreciate your help.

在 MATLAB Online 中打开

nFigures = 17;  % number of figs
subplotGrid = [5,5]; % subplot grid arrangement
nAxes = prod(subplotGrid); 
figHandles = gobjects(1,nFigures);
axesHandles = gobjects(nFigures, nAxes);
for i = 1:nFigures
    figHandles(i) = figure(); 
    for j = 1:nAxes
        axesHandles(i,j) = subplot(subplotGrid(1),subplotGrid(2),j,figHandles(i)); 
    end
end
