Hello,
I am plotting the following with semilogx:
----
F1=[200 200 200];
N1=[10000 15000 37000];
F2=[300 300 100];
N2=[12000 14000 88000];
F3=[100 200 300];
N3=[120000 14000 8000];
Ftot=[F1 F2 F3]; Ntot=[N1 N2 N3];
figure
semilogx(N1,F1,'bo')
hold on
semilogx(N2,F2,'ro')
semilogx(N3,F3,'go')
xlabel('N');
ylabel('F');
grid on
axis([min(Ntot)*0.5, max(Ntot)+min(Ntot), 0, max(Ftot)+50])
-----
The x-axis only contains 10^4 and 10^5. How do I get the plot to display each value for every vertical gridline?
Thank you.

Just add
xlim([1 128000])
