Show value within bar on flot bar chart

Question

I would like to show the value within the bar on the flot bar chart, something like this:

|
|               +----+
|               |    |
|               |    |
|               |    |
|   +----+      | 20 |
|   |    |      |    |
|   | 10 |      |    |
|   |    |      |    |
|---+----+------+----+------

data = [[1, 10], [2, 20]]

Is there a way to do this?

yeah, you're right, I've fixed it to take into account the horizontal bars. – Duhon
