Drawing a bar plot with log axes is a really bad idea. The whole
point of a bar is that you are judging the area between the top of the
bar and the y-axis. If you use a log scaled axis the distance to y=0
is Inf, and your plot isn't really meaningul.
You might want to consider using a dot plot instead. See
for a good discussion of the issues.
