plot with manual created ticks of equal length

Hello,

I am trying to create a figure that has a Y-axis similar to this figure. Although it goes from 0.01 to 100 but it was controlled in a way to make it look a bit dense. Any ideas?

and this is what I get when I do mine (these close values near 0 cant be distinguished and I need something to make it as clear as the figure above)

Their values range from ~1 to 100 but they set the ylim lower limit to 0.1 so the base plateau is nearer the midpoint of the axis range. I can't exactly read yours for sure but if it's 0.01, set it to 0.001 as starters.

my question is that although their range is 0.1 to 100 but those points around zero are still clear. How can I do to have a similar trend?

[dpb]

Those points are approx 10^0 ==> 1, not 0.

It's a logarithmic axis. To get your plateau for data near 0.01 to show up similarly in a plot as said set the lower xlim value to 0.001 for starters.

I did, but since the scale goes to 100, then it tries to make it compact near the 10^0 and hence you cant distinguish around this y-value. In the first example that I am trying to mimic, they have enforced it to be clear and I am asking if I can do something other than ylim

You can do whatever you want... :) Whether it makes any sense or not is another question.

Your data is what it is -- that it might not be as pretty as that of the other figure is a different issue. Their range over roughly two orders of magnitude while yours seems to be ...

Oh, wait a minute...how did you plot your data? Did you use semilogy or

set(gca,'yscale','logarithmic')

if you used plot? If not, that's the whole problem of you're trying to plot semi-log data on a linear plot.

Perfect. You are right :)

Thanks a lot man :)
