The required values are calculated inside the bar_plot routine, but
not returned. A simple solution is to tag on a tickv=tickv to the end
of the bar_plot declaration...

pro
bar_plot,values,baselines=baselines,colors=colors,barnames=b arnamesIn,
$
title=title,xtitle=xtitle,ytitle=ytitle,baserange=baserange,
$
barwidth=barwidth,barspace=barspaceIn,baroffset=baroffset, $
outline=outline,overplot=overplot,background=background, $
rotate=rotate,tickv=tickv

Then you may modify your code like this:

bar_plot,tab,tickv=tickv
plots,tickv,1,psym=4,color=200
xyouts, tickv[2],1,'does it work ?', /data,color=255

regards,
Greg
