how to plot a graph in log base 10 scale on the x axis

Can anyone help with the proper syntax to plot a graph in log base 10 scale for example with f on the x -axis(log base 10 scale ) and ZB on the y -axis for this expression:

for f = [1 4 10  12  17  19   24  26  34  38];
m = 10;
Zcb = 104.5; 
Zo = (1 + (0.055*(1-1i))/sqrt(f)); 
n = 800 ; 
x = 1; 
P = 800;
Z1 = 1+((m)*sin(2*pi*n*x/P));
ZB = abs(Zcb*Zo*Z1);
end

What is the loop for? What values does f have? The ones you write in the first line? If so, they are never used in the calculation!

You need to fix your "for" loop the way I showed you in your previous question.

I have corrected it .Need the syntax to do the plot.
