how to obtain data values individually while plotting graph using flot

I am drawing a bar chart like this jsfiddle code

Now the data is given like this

  data : [ [ 1, 85], [ 2, 50 ], [ 3, 18], [ 4, 8 ] ]

I need to know how will i be able to access this 85,50,18,8 individually.So that when i take my cursor to the bar chart and click it then it show me the respective values.

It should be something like series.data. But i don't know how to get the values.

What you need is simply:

// in plotclick handler - to get Y axis value for clicked item
obj.series.data[obj.dataIndex][1]

obj.dataIndex is index of the point in the data array (which in turn is available as obj.series.data).

Here's working example http://jsfiddle.net/WnC9B/24/
