How to add values over bars which I plotted? [message #42066]

Hello, everybody,

I plotted 12 bars by using bar_plot.pro. Now, what I want to do is to
add the 12 individual values over the top of 12 bars, which I often
did in EXCEL. I tried to use xyouts procedure, but I was not sure
about the x-positions where I suppose to add my vaules. How to know
the exact x positions where IDL added 12 barnames automaticly? A
further question: how to determine the distance between 2 y axises?

For example, I bar_plotted: indgen(12). now I want to add the value
[0,1,...11]
over the 12 bars I plotted. Then how to do it?

Thank you.
