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.

        function showSupportPhasesPlot(handles)
        zoom out;
        zoom off;
        %%%%SENSOR INERCIAL DERECHO
        timeMTw = handles.analysisData.timeMTw;
        %accelMTw = handles.analysisData.accelMTw;
        OrientXMTw = handles.analysisData.OrientXMTw;
        OrientYMTw = handles.analysisData.OrientYMTw;
        OrientZMTw = handles.analysisData.OrientZMTw;
        stepLimitsTime = handles.analysisData.stepLimitsTimeMTw;
        fileMTw = handles.analysisData.file;
        axes(handles.axes1);
        cla(handles.axes1);
        % hl = line(timeMTw, accelMTw(:,1));
        % set(hl, 'Color', 'm', 'LineWidth', 1);
        % hl = line(timeMTw, accelMTw(:,2));
        % set(hl, 'Color', 'c', 'LineWidth', 1);

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.
