Hello there

any help would be greatly appreciated. My data looks something like this and I would be really happy if I could reduce the gap between the bars. However
Code:
bargap(#)
seems not to work if placed among the other tablet options. Help tabplot didn't seem to bring me there.

I need a rather "low" plot, so I would wish that after .3 (after the label) the new bar starts. Bars should be much closer towards each other.
Is there any way to achieve this?

Here is example code:
Code:
 sysuse auto

gen onetwotree = 1 if rep78 <= 2
replace onetwotree = 2 if rep78 == 3 | rep78 == 4
replace onetwotree = 3 if rep78 >= 5

tabplot onetwotree foreign  , percent(foreign) showval(offset(.2) mlabp(3)) horizontal  barwidth(.1) ///
 subtitle("% of foreign", size(small)) xtitle("") bfcolor(none)

Thank you very much!

Edit: I forgot to mention I use Stata 15.
