seimlogx not working in an iteration

I am working on a MATLAB script that iterates over several values and the code is attached. For some reason it doesn't see semiology. If I plot each value of r individually, but within the script it just gives me a linear scale. A bug?

clear
clc ; clf
r = [0.90 0.96 0.98 0.99];
n=1:10000;
hold on
for i = 1:length(r)
S(i,:) = 1./((r(i)./n)+(1-r(i)));
semilogx(S(i,:))
end

The hold on command is the culprit... you're issuing it before you plot, so the linear axis is being held throughout. If you move the hold command after the first call to semilogx, it should work as intended.
