MATLAB: How to insert more space between the x-axis ticklabels and the xlabel string in the figure

axeslabel;MATLAB

I am trying to make my figure look better by inserting more space between the x-axis ticklabels and the xlabel string. However when I change the Position property of the xlabel and I try to print, using the PRINT command, to a Postscript format such as EPS, sometimes the xlabel string either moves into the axis grid or gets trimmed depending on whether its Units property is set to "data" or "normalized". This happens when the font size is big and the figure size is much larger than the paper size.

Reproduction Steps:

x=1:10;
y=1:10;
scrsz = get(0,'ScreenSize');
figH=figure('Position',[scrsz(1) scrsz(2) scrsz(3) scrsz(4)]);
plot(x,y)
set(gca,'fontsize',20)
xlabel_h=xlabel('test','fontsize',20);
set(xlabel_h,'position',get(xlabel_h,'position')-[0 0.02 0]);
print -depsc img.eps

Changing the xlabel position property results in MATLAB treating the xlabel and the axis as two independent objects so that when the PRINT command resizes the figure to fit the paper, these two objects are not where they should be relative to each other.

As a workaround, use a multiline xlabel instead of changing the Position property.

x=1:10;
y=1:10;
scrsz = get(0,'ScreenSize');
figH=figure('Position',[scrsz(1) scrsz(2) scrsz(3) scrsz(4)]);
plot(x,y)
set(gca,'fontsize',20)
xlabel_h=xlabel({'','test',''},'fontsize',20);   %use cell array to construct multiline xlabel
print -depsc img.eps

MATLAB: Does the figure title not show up in certain figures in MATLAB

It is possible that the title string is too long to be displayed on the given figure, if the figure width is not wide enough. Below are two possible workarounds:

1) Break up the title string into multiple lines, using the cell array syntax, such as:

title({'line1', 'line2', 'line3'});

2) Programmatically resize the figure until the title fully appears in the window. This example is for a title that is too wide for the plot window. It does not consider a title that does not fit vertically:

% Create some dummy data to plot
x = linspace(1,10,100);
y = rand(1,100);
% Get handle to the figure and plot the data
h=figure(1);
plot(x,y);
% Get handle to the title. The title is intentionally too long to fit on
% the default figure window.
ht=title('This is a long and big title to test for the title not appearing on the saved file',...
      'FontSize',20);
% Get the title Extent. This shows whether the title is on the figure.
titleExtent = get(ht,'Extent')
% Try to save the image. This shows that the title does not fully appear in
% the saved file.
saveas(h,'Test1','jpg')
% Set the units of the figure to normalized. Where bottom left corner of
% the screen corresponds to Position of (0,0)
set(h,'units','normalized')
% Get the position of the figure. Move the figure down towards the bottom
% left corner of the screen.
Position = get(h,'Position');
set(h,'Position',[0.1 0.1 Position(3) Position(4)])
% Perform a loop while the title is not fully in the figure window
while titleExtent(1)<0
      Position = get(h,'Position');
      % Resize the figure. Increase the figure by 5%
      set(h,'Position',[Position(1) Position(2) 1.05*Position(3) 1.05*Position(4)])
      % Force update of the plot.
      drawnow;
      % Get the new title Extent and check if the title is fully on the plot.
      titleExtent = get(ht,'Extent')
end
% Set the PaperPositionMode to auto so saveas or print captures what is
% shown on the screen.
set(h,'PaperPositionMode','auto')
% Do two different methods of saving the figure.
print(h,'-djpeg','-r600','Test2')
saveas(h,'Test3','jpg')

MATLAB: How to make the graph as big as possible on the screen

Just a little example with imshow

scrsz = get(0,'screensize');
imshow('peppers.png');
set(gcf,'position',scrsz);

Or may be :

scrsz = get(gcf,'position');
set(gca,'unit','pixel','position',[0 0 scrsz(3) scrsz(4)]);
imshow('peppers.png');
