I use the 'labelRenderer' property of AxisRenderer to provide
components for rendering the axis labels (in this case it's to add
tooltips to them) - is there a way to get a reference to the actual
instances that the 'labelRenderer' creates?
What I'm trying to do is highlight an axis label when the
user mouses over a data item in the interval that label is attached
to. I can't seem to find an obvious way to do this.
