How to define the upper limit of y-scale in a log plot

Hello, i need to plot some graphs of some curves in logarithmic scale on the y-axis and the y-scale must range from 0 to 10^-5. I want to superpose the curves on the same image, thats why the scale must be the same for all plots. I'm currently using semilogy to get a log scale, but the range is completely messed up. I've tryed using
set(gca,'yscale','log')
but again, i don't have control on the upper limits of the y-scale. What can i use to resolve this? Thanks.

You don't give any data nor attach a plot to see the issue specifically, but you set fixed axes limits on log axes the same way as you do for linear ones--use ylim (or set for low-level control or in conjunction with other properties on the axes in one call).
Simple example--
y=[10*rand(10,1), 1E5*rand(10,1)];
hAx=semilogy(y);
ylim([1,1E6])
ylim([.5,4E5])
Salt to suit for your particular case...

The problem of cannot set axis range such as ylim or xlim in log scale is becaue you cannot set log value to 0. Any value other than 0 will work.

Hi,
Please try this code:
set(gca, 'YScale', 'log')
ylim([0 1e-5])
