Plot resolution and size

Hello,

I need to save my plot - extended in one direction (width) and in 8K resolution. How can I do that? I have only this

But it is unreable. What should I do now?

[Khaled Almunem]

ImageDPI=500;
ImageSizeX=6;
ImageSizeY=4;
ImageFontSize=12;
FileLabel='plot';
FontName='Garamond';
AxisFontName='CMU Serif';

figure1 = figure(1);

axes1 = axes('FontSize',ImageFontSize,'FontName',AxisFontName);
xlim(axes1,[min(t_main) max(t_main)]);
ylim(axes1,[0 0.011]);
box(axes1,'on');
hold(axes1,'all');
h=plot(time,variable);
set(h, 'LineWidth',1)
set(gca,'FontName',AxisFontName,'FontSize',ImageFontSize)
title('title')
xlabel('Time [s]','fontsize',ImageFontSize)
ylabel('Variable','fontsize',ImageFontSize)
set(gcf,'PaperUnits','inches','PaperPosition',[0 0 ImageSizeX ImageSizeY])
print('-dpng', strcat(FileLabel, '.png') , strcat('-r',num2str(ImageDPI)))

Do not work with subplot.

Hello, I had a similar problem some time ago, The solution for me was saving the figure in EPS format, and then with illustrator force the resolution that I needed.

Hello Adam Cervenka,

since Matlab is saving figures according to "PaperPosition", "PaperPositionMode" and "resolution", these values have to be adjusted accordingly to produce figures with specific pixel-sizes:

 close all;
 clear

 % create some random data
 Data = rand(20,100);

 % open figure and plot results into subfigures
 fh = figure;
 for ik = 1:size(Data,1)
    sh(ik) = subplot(4,5,ik,'Parent',fh);
    ph(ik) = plot(sh(ik),1:size(Data,2),Data(ik,:));
    sh(ik).Title.String = sprintf('Longer Title No. %d',ik);
 end

 % set all units inside figure to normalized so that everything is scaling accordingly
 set(findall(fh,'Units','pixels'),'Units','normalized');

 % do not show figure on screen
 set(fh, 'visible', 'off')

 % set figure units to pixels & adjust figure size
 fh.Units = 'pixels';
 fh.OuterPosition = [0 0 7680 4320];

 % define resolution figure to be saved in dpi
 res = 420;

 % recalculate figure size to be saved
 set(fh,'PaperPositionMode','manual')
 fh.PaperUnits = 'inches';
 fh.PaperPosition = [0 0 7680 4320]/res;

 % save figure
 print(fh,'TestFigure','-dpng',sprintf('-r%d',res))

Kind regards,

Robert

Hi This is very useful! I tried to make an animation by stacking all the figures. Matlab somehow made the pixel length and width slightly different though I use the same code to make the figures. Your method works out in forcing the pixel length and width. Thanks!
