connectorShape property
Specifies the method that is used to generate the connector path.
Highcharts provides 3 built-in connector shapes: 'crookedLine'
(default since v11), 'fixedOffset' and 'straight'.
Users can provide their own method by passing a function instead of a string. Three arguments are passed to the callback:
- 
An object that holds the information about the coordinates of the label ( x&yproperties) and how the label is located in relation to the pie (alignmentproperty).alignmentcan by one of the following:'left'(pie on the left side of the data label),'right'(pie on the right side of the data label) or'center'(data label overlaps the pie).
- 
An object that holds the information about the position of the connector. Its touchingSliceAtporperty tells the position of the place where the connector touches the slice.
- 
Data label options 
The function has to return an SVG path definition in array form (see the example).
