is it possible to use square subplots?

if I use axis image: the problem is the gaps are too big between subplots, I would like to adjust the figure size also automatically, if possible

Answer 1

You can use "axis square" though that does not do anything for the large amount of blank space between plots. You'll need set(gca, 'Position', [x,y,w,h]) for that.

Answer 2

figure('Position', [100, 100, 400, 400]);
axes
axis('equal')  % [EDITED: or better 'square' !]

figure can be handled as a plot? its very strange for me, since I cannot set title for example! So what is the difference between figures, plots, and subplots?

[Jan]

@Mr. M: The documentation is clear:

doc figure
doc plot
doc subplot

figure creates a window. plot draws a line and creates an axes object implicitly. subplot creates an axes object with a specific position - so "subaxes" would be a better name.

For each subplot, store its handle.

     h = subplot(2,3,1);

Then set the 'position' property of h to be anything you want.

     p = get(h, 'pos');

This is a 4-element vector [left, bottom, width, height] which by default is in normalized coordinates (percentage of figure window). For instance, to add 0.05 units (5% of figure window) to the width, do this:

     p(3) = p(3) + 0.05;
     set(h, 'pos', p);

The SUBPLOT command picks standard values for these parameters, but they could be anything you want. You could put axes anywhere on the figure you want, any size you want.

And how to set figure window to be a square?

you can find an answer in the following link: http://uk.mathworks.com/help/matlab/creating_plots/aspect-ratio-for-2-d-axes.html

[Mr M.]

aspect ratio is not working for me, as I expect, for example I expect axis image is something like this: set(gca,'xlim',[-0.5 0.5],'ylim',[-0.5 0.5]);axis equal; however my plots are rectangles!
