JavaScript/jQuery PolarChart - valueAxis.label

Specifies options for value axis labels.

Type:

Object

Axis labels represent textual values for axis ticks, which are not visible by default. To specify custom settings for the value axis labels, use the label configuration object. If you need to set a common value for labels on all axes, use the commonAxisSettings.label configuration object. This object exposes the properties that can be specified for labels on all axes simultaneously. Note that a value specified for the value axis individually (in the valueAxis.label object) overrides the value that is specified in the commonAxisSettings.label object.
