Dear all,

How can I improve my figures in order to avoid the pixelation when zooming in them?

I'm using this function for creating the figures (mostly automatically generated by matlab) but I couldn't obtain the desired results.

I have tried maximizing the window, but I don't like the proportions of the text regarding the figure.

Thanks in advance,

Diego

function createfigure(A, B, C)
%CREATEFIGURE(A,B,C)
%  A:  vector of x data
%  B:  vector of y data
%  C:  table name
%  Auto-generated by MATLAB on 04-Dec-2012 03:52:43
%  screen_size = get(0, 'ScreenSize');
% Create figure
figure1 = figure;
%  set(figure1, 'Position', [0 0 screen_size(3) screen_size(4) ] );
% Create axes
axes1 = axes('Parent',figure1,'YGrid','on','XGrid','on');
box(axes1,'on');
hold(axes1,'all');
% Create title
disp(inputname(1))
t = ({[C{1}, ' - ', inputname(2), ' vs. ', inputname(1) ]});
title(t)
% Create plot
plot(A,B,'Marker','.','LineStyle','none',...
'DisplayName', {[inputname(2) ' vs. ' inputname(1)]});
% Create xlabel
xlabel(inputname(1));
% Create ylabel
ylabel(inputname(2));
X=getframe(gcf);
imwrite(X.cdata, [C{1}, '_', inputname(2), '_vs_', inputname(1),'.png'])

Well, figures look a lot better changing the last command to saveas:

% imwrite(X.cdata, [C{1}, '_', inputname(2), '_vs_', inputname(1),'.png'])
saveas(gcf, [C{1}, '_', inputname(2), '_vs_', inputname(1),'.png'])

I'm still interested in improving the appearance of my figures, so any advice is welcome...

You could give this a try (from the file exchange, by O. Woodford); I have extremely good experiences with this code. http://www.mathworks.nl/matlabcentral/fileexchange/23629-exportfig

It exports figures in the current figure window at higher resolutions.

After adding this file in your matlabpath, you should replace the latest two lines from your code into:

eval([['export_fig ' C{1}, '_', inputname(2), '_vs_', inputname(1),'.png']]
