Saving full screen multiple figures

Question

0 个投票

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’);

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.
