[Matplotlib-users] log plot problems

[Jin-chung H. <hs...@st...>]

Hi:

I encounter the following problems, most are related to log plots.  I am using
version 0.54.1 on Solaris.  Did I miss something trivial?


(1) No y tick labels when the range is less than 10, e.g.
>>> semilogy([8,5,6,4,5,6,7])

(2) The 0.3 tick mark is missing in this plot:
>>> semilogy([56,7,2,0.2,999])

(3) If we do the "linear" plot first and then overplot it with the (semi)log 
plot, the lowest Y label (1) is totally wrong and the lowest order of magnitude 
has no tick marks! e.g.
>>> plot([8,5,6,4,5,6,7])
>>> semilogy([56,7,2,0.2,999])

(4) When doing semilogx(), it is always necessary to issue the show() command 
afterwards, to see the plot.  Not so for plot() or semilogy().
