Hello,
I am plotting with "loglog". See code.
Why does the y-axis start at 100 and not 0 as I say it should be with y-lim?
MockF1=[120 100 100 140 140 180 180 100 100 100 100];
MockN1=[38500 20000 23720 4096 4532 2754 1820 16921 8241 40622 19040]; figure
loglog(MockN1,MockF1,'o')
xlabel('N');
ylabel('F');
grid on
xlim([0 500000])
ylim([0 250])

If you do not have to use a loglog plot, semilogx may be useful
semilogx(MockN1,MockF1,'o')
ylim([0 250])

Thank you. I guess I can work with a semilogx but I would prefer loglog.
A follow up question: My y-axis is now in steps of 50. 0 50 100...etc. How can I get it in to steps of 10 or whatever I choose?

set(gca, 'YTick', 100:10:180)

I think when you set ylim([0 200]) this will be interpreted as [log(0) log(200)]. That means [-Inf log(200)]

Thank you Azzi,
When I use: ylim([-inf 200]), I get as seen in the first picture
when I use ylim([-inf log(200)]), I get this
How do I get the values on the y-axis to say 100 etc and not 10^2 and so on?
