Drawing a pull plot

Dear Colleagues,

I am trying to produce a pull plot, like this one from the LEP electroweak working group at this URL:

Can anyone give me some guidance on how to proceed? I’ve managed to torture TH1’s into some pretty spiffy plots, but this kind of thing completely escapes me.

Thanks in advance for any help you can give me!

In fact that’s 4 TH1 plotted horizontally (HBAR) using option SAME.
They you can use alpha numeric labels but may be simple texts will be easier to draw the labels. It depends of your data
