I am plotting x-y plot using plot function. I want to set only y-axis as log scale and x-axis as linear? How to do that? I used loglog function but it scales both axis but I want only Y.

The best way to create that type of axes is to use the semilogy function. Alternatively, you can set the ‘YScale’ property on the axes:
set(gca, 'YScale', 'log')
***Update from Mathworks Support Team - September 2023***
As of R2023b, you can also use the 'yscale ' function.

The easiest way to do this is simply use the following command instead of plot
semilogy(x,y);
This will plot x axis on a linear scale and y axis on a log scale. Similarly, if you want to plot x axis on log scale and y axis on a linear scale, you can use
semilogx(x,y) ;
