Hi Nasser,

This time, I believe that the following expression yields the result
that you are looking for.

Needs["BarCharts`"];
BarChart[{1, 2, 3}, Frame -> {True, True, None, None},
   FrameTicks -> {{{1, "0"}, {2, "1"}, {3, "2"}}, Range[0, 3], None,
       None}, FrameLabel -> (Style[#1, FontSize -> 14] & ) /@
       {"x-axis label", "y-axis label"}]

So we get a bar chart with the bar labeled 0, 1 , and 2 on the x-axis
and below a centered label for the axis. The trick is to use the form
{tick_position, tick_label} for each ticks on the x-axis For instance,
{2,"1"} tells Mathematica to display one rather than two for the
second tick.
