Puts axes in the center of a plot. Zooming, panning and some command line manipulations allowed.

File Information
Description

AXESCENTER(AX) puts axes in the center of axes AX. If AX is not specified, the current axes will be used. Many commonly used command line options are available to manipulate the center axes, as well as zoom and pan from the figure's menubar. See the help for a fuller description of features, and a demo.

This function relies on undocumented and unsupported properties, so it may not work on some versions of Matlab.

Tested on 2007a 2007b and 2006a.

Please email me about bugs and other concerns, and email me if this doesn't work on your version of Matlab. Thanks.

Works great! NB. seems to be incompatible with new graphics in the 2014b release, hope you can modify it to sense the matlab release and operate accordingly.

This is great! Just once question. Is there a way to keep the "box" around the figure so as to sort of frame it? Here is my code

function z=graph(x)
a=0.5;
%
xmin=-0.4;
xmax=1.4;
dx=0.01;
%
x=[xmin:dx:xmax];
%
z=x.*(1-x).*(x-a);
%
plot(x,z)
axescenter

Any suggestions would be greatly appreciated. Thanks.

Does this work on 3d-plots?

I couldn't get it to work on Matlab R2011B, but I am a beginner.

This is great - using on 2010a. Doesn't seem to put scale units (e.g. 10^-14) unless I run it twice... any ideas?

Hello Robert,

There is no guarantee the axes go through the origin with any plot. This will depend on the data. But if the data is so centered, axescenter will go through the origin. Also, I cannot reproduce your claim about the xlabel. For example:

subplot(1,2,1)
plot(-10:10) % Origin-centered data
axescenter
xlabel('X Label') % Correctly placed!
subplot(1,2,2)
plot(-pi:.1:pi,cos(-pi:.1:pi))
axescenter
xlabel('X Label2') % Correctly placed.

Please email me if with some code to reproduce what you are seeing...

Great idea, two bugs for somebody to fix though:

1) It doesn't seem to work correctly with subplots (i.e. axes don't actually go through the origin)

2) It seems to change the focus from the current axes somehow, so that e.g. calls to xlabel don't work after calling axescenter. However, this is fixed by reselecting the axes.

A better functionality would be to always have the axes intersect at the origin.

This is very good; I have always wondered why MatLab does not have this feature as a standard.

I have one problem: only the "hidden" axes will show (in gray) when printing to a file (TIFF)

AXESCENTER is doing what it is supposed to do.

Sergei noticed that if the parent of the current axes is not a figure, AXESCENTER will not position correctly. He had called AXESCENTER for an axes that was in a uipanel. An update is on the way.

That works very good!

This is a good work. Great for other user from Russia

That works very well!

One remark:
gives wrong tick labels when used together with "axis equal"

I realized I should have a check that the input arg is a handle of the correct type. Update on the way.

Input checking to insure axes handle is passed.

Fixed problem of non-figure parents.
