valueAxis tickInterval

Specifies an interval between axis ticks/grid lines.

Default Value: undefined
Accepted Values: 'millisecond' | 'second' | 'minute' | 'hour' | 'day' | 'week' | 'month' | 'quarter' | 'year'

Use this option to divide the scale by ticks in a specified interval from each other. If this option is not set, ticks are automatically arranged so that their labels do not overlap each other.

In case of a continuous or a logarithmic axis, assign a numeric value to this option.

If the axis is of the date-time type, assign one of the predefined string values or an object to this option. 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.

NOTE: The specified tick interval can be changed internally if its value leads to label overlapping. If you need to prohibit automatic tick arrangement in this situation, specify the valueAxis | label | overlappingBehavior option.

To set the tickInterval option for several axis at once, use the commonAxisSettings configuration object. To set this option for an individual axis, use the argumentAxis or valueAxis configuration object.

jQuery

In the following example, the value axis tick interval is set to 0.2.
