How to plot y-axies?

Dear all, Could help me please about how to plot y-axies as seen in the figure below:

Thanks...

This is a logarithmic plot. So when you use the semilogy function, you can use

set(gca,'YTick',[1 2 8 16])

On newer versions of Matlab (I believe 2015b and later), you can use the yticks function (see this help page).

What code are you using, because I get the axis you need with the code below:

x=[250 500 600 700 780];
y=[16  8   4   2   1];
semilogy(x,y)
set(gca,'YTick',[1 2 4 8 16])
