plotting multiple plots in multiple figures inside a for loop

93 views (last 30 days)
Hi, I am trying to plot multiple plots using a for loop. we have 24 plots and I would like to divide them such that I would put 8 plots in each firgure, where each figure will have 4 columns and 2 rows.
I have used
tiledlayout(6,4)
to plot all of them in one figure but I am kinda stuck at how to seperate them into multiple figures.
If anyone can help. Thanks a lot in advanced.

The logistics of what you want to do aren't clear to me.
Do you want to have 24 figures, with each figure having 8 plots stored in a 2x4 format?

Dear Salma,
I understand that you are facing issue with ‘tiledlayout’ function while plotting multiple graphs in multiple figures using a ‘for’ loop. You want to plot 24 plots having 8 plots in each figure, where each figure will have 4 columns and 2 rows.
For your reference, I am providing a sample solution:
[X,Y,Z] = peaks(20);
% Define the number of plots and the desired layout
numPlots = 24;
plotsPerFigure = 8;
numFigures = ceil(numPlots / plotsPerFigure);
% Loop over the number of figures
for Index = 1:numFigures
figure(Index); % We have 24 plot and each figure will have 8 plot so there are total 3 plots
% Create a new tiledlayout for each figure
t = tiledlayout(2, 4);
% Loop over the plots in the current figure
for plotIndex = 1:plotsPerFigure
% Calculate the plot index within the current figure
subplotIndex = (Index - 1) * plotsPerFigure + plotIndex;
% Select the appropriate tiledlayout for the current figure
if Index == 1
t1 = t;
elseif Index == 2
t2 = t;
elseif Index == 3
t3 = t;
end
% Select the appropriate figure and tiledlayout for the current plotIndex
if subplotIndex <= 8
figure(1);
t = t1;
elseif subplotIndex <= 16
figure(2);
t = t2;
else
figure(3);
t = t3;
end
nexttile;
plot3(X, Y, Z);
title(sprintf('Plot %d', subplotIndex));
end
end
Please refer to the below documentation for more information on tiled layout:
I hope this helps!

Thank you for your reply, however, I am having the issue that the code will plot the same excat plot in all the three figures. My code looks something like the following:
for
for
for
for
if()
plot()
else
continue;
end
end
end
end
end
And following to what you suggested I putted all the for loop that I have inside the two for loops of yours so it will look like the follwing:
[X,Y,Z] = peaks(20);
% Define the number of plots and the desired layout
numPlots = 24;
plotsPerFigure = 8;
numFigures = ceil(numPlots / plotsPerFigure);
% Loop over the number of figures
for Index = 1:numFigures
figure(Index); % We have 24 plot and each figure will have 8 plot so there are total 3 plots
% Create a new tiledlayout for each figure
t = tiledlayout(2, 4);
% Loop over the plots in the current figure
for plotIndex = 1:plotsPerFigure
% Calculate the plot index within the current figure
subplotIndex = (Index - 1) * plotsPerFigure + plotIndex;
% Select the appropriate tiledlayout for the current figure
if Index == 1
t1 = t;
elseif Index == 2
t2 = t;
elseif Index == 3
t3 = t;
end
% Select the appropriate figure and tiledlayout for the current plotIndex
if subplotIndex <= 8
figure(1);
t = t1;
elseif subplotIndex <= 16
figure(2);
t = t2;
else
figure(3);
t = t3;
end
nexttile;
title(sprintf('Plot %d', subplotIndex));
for
for
for
for
if()
plot()
else
continue;
end
end
end
end
end
end
end
I think I am doing something wrog some where but I can't seem to find the error.

Dear Salma,
You are using the nested for loop code in a wrong way.
for
for
for
for
if()
for Index = 1: numFigures
% Here the Code for 3 figure and 24 plots will come
nexttile;
plot()
else
continue;
end
end
end
end
end
By placing the nested for loops within your existing code, the plotting code will execute for each combination of loop variables. Figures and plots will be created based on the conditions you have specified.

nPlots = 24;
plotLayout = [2 4];
nPlotsPerFigure = prod(plotLayout);
nFigures = ceil(nPlots/nPlotsPerFigure);
for ii = 1:nFigures
figure
tl = tiledlayout(plotLayout(1),plotLayout(2));
tl.Title.String = sprintf('Figure %d',ii);
for jj = 1:nPlotsPerFigure
nexttile();
plot(rand(1,10))
title(sprintf('Plot %d',(ii-1)*nPlotsPerFigure+jj));
end
end
