How to set semilog limit on x axis? I want it to be from 100 Hz to 15 000 Hz.

semilogx(15000*rand(50),rand(50),'bo')
xlim([100 15000])

xlim doesn't work- i've tried it before. this is my code:

 semilogx(F1(3:233,:)*1e-3,M1(3:233,:),F1(3:233,:)*1e-3,M2(3:233,:),F1(3:233,:)*1e-3,M3(3:233,:),F1(3:233,:)*1e-3,M4(3:233,:));
legend('1','2','3','4')
grid
 xlabel(' Frequency [kHz]','FontName','calibri','FontSize',35);
 ylabel('PSD','FontName','calibri','FontSize',35);
title('','FontSize',35,'FontName','calibri');
 set(gca,'FontSize',20, 'YLim', [30, 120]);
set(gca,'xscale','log');
