borderWidth property

double? borderWidth
getter/setter pair

The width of the border surrounding each slice.

When setting the border width to 0, there may be small gaps between the slices due to SVG antialiasing artefacts. To work around this, keep the border width at 0.5 or 1, but set the borderColor to null instead.

In styled mode, the border stroke width is given in the .highcharts-point class.
