Plot three graphics aligned.

Hi!

I would like to plot three graphics. But I wanto two on the first line and one on the second line, in the center of the image. I tried to use subplot but it didn't worked (or I don't know how to use it right).

It is more or less like this:

 AAA AAA
   AAA

Can anyone help me with that?

Thanks very much for you time.

This may be what you want to do:

t = linspace(0,10*pi);
for k1 = 1:3
    y(k1,:) = sin(t*k1);
end

subplot(2,2,1)
plot(t,y(1,:))
subplot(2,2,2)
plot(t,y(2,:))
subplot('Position',[.33 .1 .35 .35])
plot(t,y(3,:))

produces:

See the documentation for subplot under ‘More About’ and ‘Tips’.

Or, if you want a layout exactly like you showed, you can switch from 2,2 to 2,3. Modify Star's code like this:

t = linspace(0,10*pi);
for k1 = 1:3
    y(k1,:) = sin(t*k1);
end

subplot(2,2,1)
plot(t,y(1,:))
subplot(2,2,2)
plot(t,y(2,:))
subplot(2,3,5)  % <--- Changed line.
plot(t,y(3,:))

You can do further tweaking of size and location by asking suplot to return the handle and setting the 'Position' property of the subplot with the set() function:

set(hPlot, 'Position', [left, top, width, height]);
