One of the most frustrating tasks I encountered while using MATLAB was to output and store figures that were high resolution and the font size would be legible when copied into double column journals. Copying the figures directly (Edit -> Copy figure) works well but I always preferred to have my scripts run and have the files stored automatically to an assigned folder. The attached code is what I currently used. While the coding is very simple, it took quiet a while to assimilate those few lines to generate the quality of figure I was looking for.
%% Plot figure grid on; ylabel('y-axis label [units]','fontsize',18); %Label y-axis with a font value of 18 xlabel('x-axis label [units]','fontsize',18); %Label x-axis with a font value of 18 set(gca, 'FontSize' ,18) ; %Set font size of x and y axis values set(gcf, 'Position', [ 1 1 960 540] ); %Set dimension of figure set(gcf, 'Color', 'w'); %Change background of figure from grey to white set(gca,'GridLineStyle','- -') %Define grid line pattern (optional) ti = get(gca,'TightInset') %Remove extra spacing around figure set(gca, 'LooseInset', [0,0,0,0.01]); %Depending on the figure, you may need to add extra spacing [left bottom width height]) print( '-dtiff', ['figures\' filename ], '-r600'); %Change "-r600" to the required DPI
Another issue I have also encountered with outputting the images to file is the dimensions of the stored image may not match the image on screen. The following script re-sizes the output page to the dimensions of the on screen image. You would be required to change the pixels to inches.
% Use the following site to convert pixels to inches: http://pixelyzer.com/image_size_calculator.html width = 12.8; % 960 pixels converted to inches height = 7.2; % 540 pixels converted to inches set(f, 'PaperUnits', 'inches','PaperPosition',[0 0 width height]);% Remember to set "f=figure" print( '-dtiff', ['figures\' filename ], '-r600');
