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

Hello,
tahnk you for your answer, here is an example :
device, decomposed=0,retain=2
loadct,39,/silent
tab = indgen(4)
bar_plot,tab
xyouts, 2,1,'does it work ?', /data,color=255
plots,1,1,psym=4,color=200
result : http://nau.cetp.ipsl.fr/bar_plot.png

I think they are [0,1,2,3,4,5], but you may want to show some code to
be sure.
