Set the default pathfinder algorithm to use for this chart. It is possible to define your own algorithms by adding them to the Highcharts.Pathfinder.prototype.algorithms object before the chart has been created.
The default algorithms are as follows:
straight: Draws a straight line between the connecting
points. Does not avoid other points when drawing.
simpleConnect: Finds a path between the points using right angles
only. Takes only starting/ending points into
account, and will not avoid other points.
fastAvoid: Finds a path between the points using right angles
only. Will attempt to avoid other points, but its
focus is performance over accuracy. Works well with
less dense datasets.
Default value: straight is used as default for most series types,
while simpleConnect is used as default for Gantt series, to show
dependencies between points.
