Range Padding

Padding can be applied to the minimum and maximum extremes of an axis range by using the rangePadding property. Numeric axis supports the following types of padding.

  • Round
  • Additional
  • Normal
  • Auto

When the rangePadding is set to None, minimum and maximum of the axis is based on the data.
