IDL> print, !version
{ x86_64 darwin unix Mac OS X 8.2.3 May 2 2013 64 64}
Here is the problem I have found. Not sure whether other people have reported this or not. I discovered this while making some plot using data from a simulation. So the numbers below might look strange to you.
IDL> print, mean_b
0.0024484981
IDL> print, maxb
0.047594825
IDL> print, minb
1.0000000e-18
IDL> a=plot([0,999], [minb,maxb], /ylog, yrange=[mean_b, maxb])
The y axis of this plot is totally wrong. There is something wrong with the use of YRANGE in this case. However, if I do the following, the resulting figure looks fine.
IDL> a=plot([0,999], [minb,maxb], /ylog)
IDL> a.yrange=[mean_b, maxb]
This sounds like a bug to me, but I'm not sure whether other people can reproduce this or not.

Hi Xin,
Yup, this is a bug, just reported last week & with the workaround you've found. Would you please send a quick email to Tech Support so they can add you to the ticket? It's IDL-68781.
