Artefacts in drawing histogram with "bars same" option

ROOT
1

On the attached file you can see green lines covering X axis for empty bins of the green histogram. They appear because this histogram is draw with the “same” option. Can anything be done about that? Perhaps I can somehow force redrawing of the axes?

I attach image and macro used to create it.

Since picture is to large to be properly displayed in this forum, I attach smaller version.

gPad->RedrawAxis();

BTW. you can “EDIT” your posts, and so you can also replace attached pictures. No need to post/create a new message.
