After a lot of digging and testing, I've managed to get this working - still not sure if this is the best way (probably not).

Chart.series.get(someId).graph.attr('stroke-width', '5')

Unfortunately, this is just getting into the actual DOM element and changing the value of the property of a single element, so if you need to change the stroke width, and the styles of the markers on this line, you'd have to loop through all elements, and apply changes manually.

UPDATE: Ok, there's a better way

But this is using the private API, so if the library changes thins, your code will not work:

Chart.series.get(someId).onMouseOver() and Chart.series.get(someId).onMouseOut().

This actually fires the defined hover-state.
