Label bars with their values

[rwstauner]

There are several ways to do this, but none that are perfect:

• I tried it at the bottom on the bar, which was ok (if you don't mind fully vertical), but when the bar is short it falls off
  
• We could add another row below the axis but I haven't seen any other graphs do that before

Then I tried it at the top of the bar with a semi-transparent background and found them to be surprisingly legible... they overlap the next bar ever so slightly and yet you can still see the edge of the bar and the variance whiskers. Even when they overlap each other I can discern which is which.

What do you think?

seems okay, but I would maybe make the labels just a little bit smaller to avoid overlaps?

I shrunk the text a bit and moved the labels to be more centered over the bar.
What do you think?

It also doesn't look terrible completely vertical (-90 transform) but still the text can overlap when there are too many bars
