Matlab Gui axes problem

Hi everybody,

I have a problem related to the axes in matlab Gui. I have 3 axes and I don't know why two of them have their 'Xaxis' linked. I don't have linkaxes function in any of them. I think the problem is somewhere in this part of the code. It would be great if any of you could help me.

Your life would be a lot easier with these problems if you would just pass the explicit axes handle to the plotting and limit setting functions rather than bringing an axes into focus and then relying on it being the active axes, e.g.

h2 = line( handles.axes3, timeMTw2, OrientXMTw2);
...
yLim3 = get(handles.axes2, 'YLim');

etc

Do you mean by 'have their axes linked' that when you zoom in one the other always zooms by the same amount? And if so more information would be useful. You have 3 axes in that code, you haven't said which two appear to be linked.

[Itziar Uzqueda]

Well, axes1 and 2 are the ones that appear linked. Yes, linked means that when doing zoom but also the axes1 signal appears cut because its 'Xaxis' is the same as the second.

[Stephen23]

I second Adam's comment. Your code would be simpler and much more reliable by always passing and using explicit graphics handles. Reliable code never uses gca, gcf, or the like, and does not rely on bringing some graphics object into focus. Those commands are just asking for trouble, exactly as you are experiencing now.

[Itziar Uzqueda]

Yes, I have followed your advice but it still doesn't work. I don't know what else can I do.
