Matlab: Overlapping subplot titles

问题

I'm using subplot which contains three different plots. Each plot has its own labels and title.
The problem is that I have to maximize the plot when I save it. Otherwise, the texts will overlap each other.
When I maximize it, the subplot's label text will appear little blurry in the image, even if I use ESP format or any vector format.
How can I resolve this issue?

回答1:

For the title overlap issues, you can produce multiple lines of title text use a cell array of strings as the input parameter of title():

title_text = {'first line', 'second line', 'third line'};
title(title_text);

And it works for label text too.

In addition to Da Kuang's answer, if you would like to keep your titles and labels on the same line, you could change the font size

a = axes;
t = title('My Really Long Title');
l = xlabel('My Really Long x label')
set(t, 'FontSize', 8)
set(l, 'FontSize', 8)

I'm not sure why your labels are blurry, but I can help with the overlap.

I never use subplot when I want to save images (eg. for a paper). What I do instead is create each axes individually, which allows a lot more control over each of them.

Below is a rather general example, which illustrates how to generate an arbitrary grid of axes with much finer control over their placement than subplot allows. Of course, with only 3 axes, you don't really need the loop, but I'm sure you can adapt this to fit your needs.

% first create the figure
figPos = [200 200 800 500];
figure('Color', 'w', 'Position', figPos)

% next, determine how much padding you want on each side of the axes, and in
% between axes. I usually play around with these, and the figure size until
% the layout looks correct.

leftPadding = 50/figPos(3); % the space at the left of the figure
rightPadding = 25/figPos(3); % the space at the right of the figure
horizPadding = 80/figPos(3); % the space between axes (horizontally)
topPadding = 30/figPos(4); % the space at the top of the figure
bottomPadding = 50/figPos(4); % the space at the bottom of the figure
vertPadding = 120/figPos(4); % the space between axes (vertically)

% set up the grid size
nHorizAxes = 2;
nVertAxes = 3;

% figure out how big each axes should be
horizPlotSpace = 1-leftPadding-rightPadding-(nHorizAxes-1)*horizPadding;
vertPlotSpace = 1-topPadding-bottomPadding-(nVertAxes-1)*vertPadding;
width = horizPlotSpace/nHorizAxes;
height = vertPlotSpace/nVertAxes;

myAxes = zeros(nVertAxes, nHorizAxes);

% create some sample data to plot for illustrative purposes
x = linspace(0, 2*pi);
y = sin(x);

for iRow = 1:nVertAxes
    for iCol = 1:nHorizAxes
        % calculate the position
        left = leftPadding+(iCol-1)*(width+horizPadding);
        bottom = bottomPadding+(iRow-1)*(height+vertPadding);
        position = [left bottom width height];

        myAxes(iRow, iCol) = axes('Position', position);
        plot(x, y)
        xlabel('Test Label')
        ylabel('Test Label')
        title(sprintf('axes(%d, %d)', iRow, iCol))
    end
end

Those answers should help but here are some other things to try, depending on the cause of the overlapping text:

Change the figure's size so there's room for the text. For example:

set(gcf, 'PaperSize', [5 7])

Change the size of the subplots.

s = get(gca, 'Position');
set(gca, 'Position', [s(1), s(2), s(3), s(4) * 0.5])
