How to plot histogram ratios as bar chart with bottom set to y=1

Dear Users,

I would like to plot histogram ratios in form of bar charts as in the following plot:
example_ratioBar
(note the in this image the ratios have been shifted by -1, but I would like to do this without shifting)
I’ve managed to plot the ratios as dots, as well as bars with bottom y=0 which is default. Is there a command to change the bottom so that they start from 1?

In the case of TRatioplot the bottom plot is a graph.
The drawing option can be changed with:
SetH1DrawOpt
SetH2DrawOpt
SetGraphDrawOpt
(see doc)
