enabled: boolean
Default value: true

Enable/Disable Others/Previous slices.

maxOthersFraction: number
Default value: 0.6

Max size of others slice, as a fraction of 1. If others slice is bigger than this, it will be made smaller and other slices proportionally expanded.

maxSlicesVisible: number
Default value: 15

Max number of slices to show. All remaining slices will be replaced by 'Others' slice.

minSliceFraction: number
Default value: 0.01

Minimum slice size as fraction of full pie. All slices smaller than that are replaced with 'Others' slice.

minSlices: number
Default value: 1
Introduced in version 1.12.0.

Minimum number of slices the pie needs to have for it to show the Others slice. Note that once this limit is reached the Others slice may also contain all but one of the slices - this setting does not limit the minimum number of slices that are shown at once in such case.

If you set this property to a value greater than 1, it might be useful to set slice.minFraction to a value of 0.01 or greater.

navigationFraction: number
Default value: 0.15
Version 1.12.0: the settings correctly applies to Others slice.

Others and Previous slice size as fraction of full pie. Previous will always be this big. Other will be at least this big but no bigger than maxOthersFraction.
