Hi all,
The first below figure is the plot I can make while the second is the example plot that has different scales on x-axis as highlighted yellow.
I would like to make a plot that has different scales on the same axis the same as the example. I would appreciate it if you could provide some suggestion on this matter.
Thank you.

Either you can use something like
set(gca,'xscale','log')
if that brings you close enough.
If you want to plot on some other scaling you can do something like this:
x = logspace(-1,3,41); % just some arbitrary points in x-direction
y = x.^.43 + 0.3*x.^1.32;
plot(x.^.5,y);
x4l = logspace(-1,3,9);
for i1 = 1:9,
xStr{i1} = sprintf('%3.1f',x4l(i1));
end
set(gca,'xtick',x4l.^.5,'xticklabel',xStr)

Thank you so much!. Once reading your reply, I just have noticed that the x-axis of my example is in the form of logarithm. Therefore, I apply semilogx function together with xticks & xticklabels.
Thanks again :).
