plotyy y axes overlap

Hi, I have a real time plot and when I try to plot using plotyy the axes overlap and the two plot lines are created slighty to the left if the last x value is not integer. how can i prevent x axes overlapping and have the graph lines plot the right way on the plot? thank you

 set(hObject,'CurrentAxes',handles.Axes1);
 hold(handles.Axes1,'on');
 set(handles.Axes1,'units','normalized')
 cah = get(hObject,'CurrentAxes');

 [ax,hlines(1),hlines(2)]=plotyy([handles.Axes1],x,y{1},x,y{2});

h = findobj(0,'type','axes','Tag','Top');
delete(h)
[ax,hlines(1),hlines(2)]=plotyy([handles.Axes1],x,y{1},x,y{2});
set(ax,'xlim',get(handles.Axes1,'xlim'))
set(ax(1),'xcolor','black')
set(ax(2),'tag','Top','xcolor','black')

Perhaps you want to set the 'XLim' property manually instead of letting Matlab set it dynamically.
