How to make only x-axis invisible (y-axis stays visible)?

I have two axes (top, bottom) in a GUI. I do not want the x-axis of the top ghraph to be present (because it is the same as the bottom x-axis). I could not find how to handle separately the x and y axis visibility.

without seeing your code, a simple way is just to set the 'xtick' property to []
plot(randn(100,1));
set(gca,'xtick',[])

Does this get closer?
subplot(211)
plot(randn(100,1))
set(gca,'xtick',[]);
set(gca,'xcolor',[1 1 1])
subplot(212)
plot(randn(100,1))

Sorry, no. It makes the axis white but I have a picture behind the graph. So white axis (and actually any colors) are visible in my case. I do not want the x-axis at all.

This Question is posted in 2013, but still last week got more than a thousand views, and I also needed this info, and I got very helpful information in this post, but surprizingly later I got an other solution in Matlab documentation and that was not yet here, and it is probably the smalest code, and I tested it and it worked nice, so I decided to addd it, here it is:
axis off ;
And thats it your axes are gone.

Dear Muhammad,
First, this solution was already published (see above).
Second, in 2013 this command did not exist.

Hi, axes('Color','none','XColor','none');
works for me Bests Johann

Hi,
Try:
ax1.YAxis.Visible = 'off'; % remove y-axis
ax1.XAxis.Visible = 'off'; % remove x-axis
Hope that helps, J

How about removing only one y axis (say right side) and not both?
Thanks

@Ankit Labh ax1.Box = false;
This removes both the top and right side axes, but not the left and bottom axes.

Try the following:
h = gca;
h.XAxis.Visible = 'off';

This solution might be overkill, but you can get that effect with my File Exchange program 'oaxes', available here: http://www.mathworks.com/matlabcentral/fileexchange/30018. The following will show only a y axis at the left edge of the plot:
oa = oaxes;
oa.XAxisLine = 'off';
oa.XLabel = '';
oa.YLabel = '';
oa.Arrow = 'off';
oa.Origin = [-Inf -Inf 0];
% If you want the normal y label to be visible:
ylabel('my y axis...')
set(get(gca,'YLabel'),'visible','on')
This should get you close to what you are looking for. The oaxes documentation will give you more information about the properties used in the example above, including an explanation of the difference between the oaxes 'YLabel' property which is set to empty above, and the parent axes' 'YLabel' text object. The main difference in appearance I am getting is that the oaxes ticks are bidirectional (they extend out on both sides from the axes line), while a normal axes has ticks that only extend to one side. Currently, there is no way to change this in oaxes, but I might add it in a future release.

h = axes;
plot(h,rand(10,1));
pos = get(h,'Position');
new_h = axes('Position',pos);
linkaxes([h new_h],'y');
pos(3) = eps; %Edited here
set(new_h,'Position',pos,'XTick',[],'XTickLabel',[]);
set(h,'Visible','off');

Yes, it works, although it is a workaround and not a solution.

Turn Box off, it usually works.

I solved something similar that way:
set(axis_h,'XColor',axis_h.Parent.Color);

Ran in:
This wasn't an option when the question was originally asked, but now you can change the Visible property of the appropriate ruler object that is part of the axes. Compare the axes without the ruler being changed:
ax = axes;
plot(ax, 1:10);
with one that does have the ruler turned off.
figure
ax2 = axes;
plot(ax2, 1:10);
% Get the ruler for the X axis
x = ax2.XAxis;
% Make it invisible
x.Visible = 'off';
