I have a pie chart that has subvalues and it seems to me that slices with subvalues have an edge around them and I want to be able to remove these.
Is there a way to remove these edges from the settings ?
The white lines mark expandable slices. You can configure them through slice.expandableMarkStyle. For example:
slice.expandableMarkStyle
slice: { expandableMarkStyle: { lineWidth: 0 } }
