How to modify the values of axis (image explaining better)

Hello, i hope you are all safe and healty. Sorry for talking your time but 
i would really need some help here. 
I have the following graph, but i tried with many ways and i 
can't find the right one to solve my problem.
I want to somehow separate the numbers that are one on top of the other
(that happens because the number's lenght is big, because i have numbers like 0.015625 and 0.03125). 
Any ideas? Thank you very much!!!! Much obligded. (running MATLAB 2014b)

Just check the first example of mathworks here. You can solve your problem by using xticks (and eventually xtickslabel if you want to). Ex:

% your normal plot
xticks([0.01525,0.125,0.25]) % add your other wished ticks

Thank you very much for your time and your answer sir!! I have one more thing to ask. I am running MATLAB 2014b, so the xticks function doesnt exist. So i tried the following,

set(gca,'XTick',[0.015625, 0.03125, 0.0625, 0.125, 0.25, 0.5, 1.0] );

set(gca,'xticklabel',({'0.015625','0.03125','0.0625','0.125','0.25','0.5','1.0'}))

but i got the same result as before.

The problem is that the first 3 labels are overlapping, you will only make it clean if you remove two of them. If you use the same labels it is clear that the result will be the same. If you really need that all ticks be there an alternative is to rotate them:

set(gca,'XTickLabelRotation',90)

Great!! Thanks a lot sir!! Hope i could somehow return the favor!! Be safe
