How to add a tooltip to a FLOT graph

This is the full code that I am trying to use. It works without the tooltip functions but not when including them

The code produces a graph with 2 lines and bars. How do I add a tooltip without it messing up my graph and actually add some interactivity?

Solution

There were a number of different errors in your fiddle:

The grid options were missing the necessary hoverable: true
Another missing # before placeholder in in $("placeholder").bind("plothover", ...
} else( should be } else { (from empiric's comment)
A superfluous var in var y = item.datapoint[1].toFixed(0); (or replace the , with a ; between the two var statements)
Change position: 'abolute' to position: 'absolute' in the CSS of the tooltip

Some of the errors are found when looking at the console of your browser.
