linkaxes does not work like expected (or hoped)

Hi,

i wrote the following (minimal) code:

clear all
close all

X = -3:0.3:3;

a = 1;
b = 2;
c = 1;

Y = a + b * (X - c).^2 + 0.4* rand(1,length(X));

h = figure;
a1 = gca;
a2 = axes('xaxislocation','top','yaxislocation','right','color','none');

hold on

hData = scatter(X,Y);

linkaxes([a1 a2]);

axis([a1 a2], [min(X) max(X) min(Y) max(Y)])

hold off

Apparantly, I wanted to have a graph with axes on all 4 sides. I thought with "linkaxes" i can link the axes in a way that they are always scaled in the same way. For the x-axes it seems to work well, but the y-axes appears to have some different scaling factors (which you can see, if you resize a little bit the graph-window.

Can anybody explain what i did wrong?

Thanks!

Your code works fine for me for both x and y axes on resizing.

They have the same range. this works also perfect for me. Just the length of the axes is different. In the picture you can see what i mean (eg. the "30" left and right is not at the same heigth.... now i also saw that the data are going down below the graph.

EDIT: now also with the promised graph :-)

Can't reproduce that effect here--what Matlab release and OS? Perhaps try changing the renderer setting if it's somehow related to a local video driver issue.

Matlab R2011b and Windows 8. I could solve the problem by adding

 set(a1, 'Position', [0.13 0.13 0.74 0.74]);
 set(a2, 'Position', get(a1, 'Position'));

I was just thinking "linkaxes" is doing that automatically

Probably a version enhancement/bug fix since that release.
