sample_deltap.fig

In the sample image, I would like to have xtick labels at 0 line too.

The word too implies showing the tick labels twice ... This just repositions the axis, which is what you're after, I think:

ah = subplot(2,1,1) ;
plot(rand(20,1), randn(20,1), 'bo' ) ;
set(ah,'XAxisLocation','origin')

Thanks. Yes, just drawing a line at zero is easy(and I have already done that in the sample image), but having the xticks and corresponding labels at two places is what I was trying to implement

I have never seen that in any proper data graph. Why do you want to do that? To me, it seems that it will be confusing. You could add gridlines as an alternative, using grid on, for instance.
