Axis labels represent textual values for axis ticks, which are not visible by default. To specify custom settings for the argument axis labels, use the label configuration object. 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 at once. Note that values specified for the argument axis individually (in the argumentAxis.label object) override values that are specified for all axes (in the commonAxisSettings.label object).
Specifies the text for a hint that appears when a user hovers the mouse pointer over a label on the argument axis.
When implementing a callback function for this configuration option, use the argument value to be displayed in a label. This value can be accessed using the fields of the object that is passed as the function's parameter. Alternatively, you can use the this object within the function. This object has the same structure as the object passed as a parameter.
For general information on data formatting, refer to the Data Formatting topic.
When axis labels overlap each other, you can rearrange them by setting the overlappingBehavior option. It accepts the following values.
Hides certain axis labels leaving more space for the others.
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:
Use the argumentAxis.label.format.precision option instead.
