MATLAB: Are the axes not aligned correctly when using PLOTYY on a subplot in MATLAB 7.0.1 (R14SP1)

alignmentaxisMATLAB

I use the PLOTYY function to create one of the subplots in my figure window by executing the following in the MATLAB Prompt:
t = linspace(-10,10,128).'*1e-12;
I = t;
I1 = t.^2;
w = t;
S1 = t;
p = t.^2;
figure('DefaultAxesFontSize',12,'Position',[0 400 1000 650])
subplot(2,2,[1 2])
line
subplot(223)
[hax,hp(1),hp(2)] = plotyy(w*1e6,S1,w*1e6,p);
set(hax,'XLim',[1.062 1.072])
set(hax(2),'Position',get(hax(1),'Position'))
set(hax(1),'XMinorTick','on','YMinorTick','on')
However, the subplot resulting from the PLOTYY function has two axes that do not align correctly.

Best Answer

The ability to align axes correctly when using PLOTYY on a subplot is not available in MATLAB 7.0.1 (R14SP1).
To work around this issue, execute DRAWNOW to flush the buffer between the two SET commands that modify the size of the two axes as follows::
set(hax,'XLim',[1.062 1.072])
drawnow
set(hax(2),'Position',get(hax(1),'Position'))
