function , Y-axis automatic logarithmic scale is expand to B^0 (i.e. 1)
in almost all cases.
In step 2, it is said 
/* If minimum is less than 5 (i.e. original source values less than
B^5, B being the base of the scaling), or if minimum and maximum
are in different increment intervals (means, if minimum and maximum
are not both in the range [B^n,B^(n+1)] for a whole number n), set
minimum to 0, which results in B^0=1 on the axis. */
I do not agree with this comment because on a log scale, "1" has no special
meaning: it is not the origin, like "0" is on a linear scale. I would
propose a patch to suppress this part, but there are may be some good
reasons to expand to 1?
I opened bug 96871  about this.
Thanks in advance for your help.
