Sticky tracking of mouse events. When true, the
mouseOut event on a
series isn't triggered until the mouse moves over another series, or
out of the plot area. When false, the
mouseOut event on a series is
triggered when the mouse leaves the area around the series' graph or
markers. This also implies the tooltip when not shared. When
stickyTracking is false and
tooltip.shared is false, the tooltip
will be hidden when moving the mouse between series. Defaults to true
for line and area type series, but to false for columns, pies etc.
Note: The boost module will force this option because of technical limitations.
