[OT] Histograms on logarithmic scale (constant bin size on logaritmic scale)

Hello ROOTers,

   i'm facing a small issue, not necessarily correlated with ROOT: i want to build an histogram with the energy on the X scale put in logarithmic scale.
I'm building the histogram with the Fill() function. However, since the bin width is constant on the x scale, whenever i'm changing to log x scale lower bins appears larger than bigger bins (obviously). One solution to this problem could be to fill not directly the x axis with Fill(x) but Fill(Log10(x)). This works but the x axis appears with linear labels while it should be logarithmic.

My question is twofold:
1) is it possible to solve this without using Fill(Log10(x))? 2) if it is not the case, how is it possible to change the label of the axis?
