Histograms are nearly always uniformly spaced and there are actually very few software packages that allow non-uniform bin widths.

histogram([[1.5..1.65,50],[1.65..1.7,20],[1.7..1.8,30]])

thank you both, I'll make some tries...
I understand that it's not easy to handle this kind of problem.
I thought there was a way to input something like 0..10 or 0::10. This was the sense of my question...
I'll try as you suggest with some examples.
However, for now, I don't find histogram in Geo; I'm searching better...
