Hello, I have the two following plots which I am trying to superimpose. I want figure two to be super imposed on figure 1 but figure 1 has a log scale on its x axis. Can someone please help.
semilogx(f,x) %figure 1
stem(y,z) %figure 2

Why not use SUBPLOT?
subplot(1,2,1)
stem(y,z)
supbplot(1,2,2)
semilogx(f,x)
By the way, a figure is the window that holds the axes object. If you want them on the same axes, do
semilogx(f,x)
hold on
stem(y,z)

thank you for your answer, I have used the second option. but how can i rescale the axis of stem(y,z) to become linear for the values of y instead of logarithmic

If that is your concern, do this:
x = 1:10:10000;
semilogx(x,.3*x.^3);
axx = gca;
ax = axes;
plot(x,x.^5,'r')
set(ax,'visible','off','ylim',get(axx,'ylim'))
The last line scales the ylimits of the second axes to match the first axes. If you don't want to do this, just take the part out where ylim is set.

Perhaps the MATLAB File Exchange contribution plotxx would be of use to you.
