Hi everyone,

I would like to ask how can I change orientation and resolution (at least 300dpi) in the printed pdf file of a figure with subplots? The code below has a portrait orientation. The code I have prepared is the following:

A = randn(500,7);
VARNAMES = {'1','2','3','4','5','6','7'};
time = datetime(1950,1:500,1);
figure;
figure; for k = 1:7
subplot (4,2,k)
filename = plot( time' , A( : , k ) );
xlim(datetime([min(time) max(time)]))
title ( VARNAMES(k));
hold on
end
set(filename,'PaperOrientation','landscape'); 
print ('fig1', '-dpdf', '-fillpage', '-r300')

But i get following error message 'Error using set

There is no PaperOrientation property on the Root class.'

Also, does this print setup secures a 300dpi coloured resolution?

Instead of the set function, use the orient function to set the orientation that is used when saving or printing

The print function you are using should give you the required dpi.
