Decides how to arrange axis labels when there is not enough space to keep all of them.

Type: String
Default Value: 'hide'
Accepted Values: 'hide' | 'none'

When axis labels overlap each other, you can rearrange them by setting the overlappingBehavior option. It accepts the following values.

  • hide
    Hides certain axis labels leaving more space for the others.
  • none
    Leaves axis labels overlapped.

When using the widget as an ASP.NET MVC Control, specify this option using the PolarChartOverlappingBehavior enum. This enum accepts the following values: Hide and None.

Specifying this option with the "enlargeTickInterval" and "ignore" values is deprecated.


Indicates whether or not axis labels are visible.

Type: Boolean
Default Value: true
