I noticed that bin setting of "Histogram" command probably limited at 1 as minimum for log bins (I'm not sure about other bin settings).

If we can set more small number as 0.1, more fine histogram will be drawn.
Could you consider this?

A bin setting of c means that the bins are c,c^1,c^2,c^3 etc. That also includes negative powers of c. So on the log axis it is ...,-2log(c),-log(c),1,log(c),2log(c),3log(c),...

So if you want small bins you need to make log(c) small. For example c=1.1,1.01,1.01. For values close to 1

log(1+delta) is approximately delta

Thank you David.
That's I'm looking.
I did not well understand the log calculation and the setting...
Anyway, I can use Histogram as I expect.
