JavaScript/jQuery PolarChart - argumentAxis.tickInterval
Use this property to divide the scale by ticks in a specified interval one from another. If this property is not set, ticks are automatically arranged so that their labels do not overlap each other.
In case of a numeric axis, assign a numeric value to this property.
If the axis is of the date-time type, assign one of the predefined string values or an object to this property. The object's fields specify the number of days, hours, etc.
When you use a logarithmic axis, ticks are generated on a base of powers. For example, assume that the logarithm base is 10. Then, if the tick interval is 1, ticks are generated at 0.01, 0.1, 1, 10, 100, 1000, 10000, etc. If the tick interval is 2, ticks are generated at 0.1, 10, 1000, etc.
To set the tickInterval property for several axes at once, use the commonAxisSettings configuration object. To set this property for an individual axis, use the argumentAxis or valueAxis configuration object.
