Saving full screen multiple figures

27 views (last 30 days)
Hello,
I have four files with ten columns of data. They have common x-axis, array of t.
I am plotting them using for loop
The code looks something like below;
For i=1:10
figure(1)
handle1(i)=plot(t(:,1), File1(:,i));
Legend1{i}=sprintf('Run number: %d',i);
hold on
figure(2)
handle1(i)=plot(t(:,1), File2(:,i));
Legend2{i}=sprintf('Run number: %d',i);
hold on
figure(3)
handle3(i)=plot(t(:,1), File3(:,i));
Legend3{i}=sprintf('Run number: %d',i);
hold on
figure(4)
handle4(i)=plot(t(:,1), File4(:,i));
Legend4{i}=sprintf('Run number: %d',i);
hold on
end
legend(handle1,Legend1, ‘location’, ‘northwestoutside’);
legend(handle2,Legend2, ‘location’, ‘northwestoutside’);
legend(handle2,Legend2, ‘location’, ‘northwestoutside’);
legend(handle2,Legend2, ‘location’, ‘northwestoutside’);
Now, saving figure after legend will reduce the figure aspect ratio. I would like to save figure in full-screen mode.
i.e.saveas(figure(2), ‘Figure2.tiff’,’Tiff’);
I did some search and found the following code
FigH = figure('Position', get(0, 'Screensize'));
F = getframe(FigH);
I am unable to figure out as to how I can incorporate figure number inside above-mentioned command. i.e. inside figure(‘position’, get(0,’Screensize’))
I am learning matlab now. I also welcome any additional comment on the code itself.

Are you trying to save 40 figures? Or 4 or 10?

4 figures in total. Each will have 10 lines.

Try this:
clear all;
close all;
clc;
format long g;
format compact;
fontSize = 18;
fprintf('Beginning to run %s.m ...\n', mfilename);
% Create sample data.
File1 = rand(5, 10);
File2 = rand(5, 10);
File3 = rand(5, 10);
File4 = rand(5, 10);
t = rand(5, 10);
handle1 = figure;
handle2 = figure;
handle3 = figure;
handle4 = figure;
plotColors = jet(10);
for k=1:10
thisColor = plotColors(k, :);
figure(handle1)
plot(t(:,1), File1(:,k), '-', 'Color', thisColor);
legendStrings{k}=sprintf('Run number: %d',k);
hold on
figure(handle2)
plot(t(:,1), File2(:,k), '-', 'Color', thisColor);
hold on
figure(handle3)
plot(t(:,1), File3(:,k), '-', 'Color', thisColor);
hold on
figure(handle4)
plot(t(:,1), File4(:,k), '-', 'Color', thisColor);
hold on
end
figure(handle1);
legend(legendStrings, 'location', 'northwestoutside');
exportgraphics(handle1, 'Plot1.png'); % Save figure to disk.
figure(handle2);
legend(legendStrings, 'location', 'northwestoutside');
exportgraphics(handle1, 'Plot2.png'); % Save figure to disk.
figure(handle3);
legend(legendStrings, 'location', 'northwestoutside');
exportgraphics(handle1, 'Plot3.png'); % Save figure to disk.
figure(handle4);
legend(legendStrings, 'location', 'northwestoutside');
exportgraphics(handle1, 'Plot4.png'); % Save figure to disk.
% You can maximize each one before saving if you want, like this:
g = gcf;
g.WindowState = 'maximized';
fprintf('Done running %s.m.\n', mfilename);

Thanks. Just a note: I used saveas(gcf,..) instead of exportgraphics as I was getting error with it.

exportgraphics() only started with r2020a.
