argumentAxis minorTickInterval

Specifies the interval between minor ticks.

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

To divide a lengthy chart axis into shorter segments, major and minor ticks are used. Major ticks are accompanied with axis labels. Between each pair of neighboring major ticks, several minor ticks reside. Minor ticks are required when major ticks are far from each other. To set a custom minor tick interval, use the minorTickInterval option. If this option is not set, minor ticks are arranged automatically.

In case your axis displays numbers, assign a numeric value to this option. If the axis displays dates, assign one of the predefined string values. To set the interval to several days, hours, etc., assign an object with the corresponding field specified (days, hours or another field). Note that this object must contain only one of the fields described in this section.

NOTE: The minorTickInterval option can be applied to a continuous axis only. For logarithmic axes, use the minorTickCount option.

In the following example, the argument axis minor tick interval is set to 20 minutes.

<div id="chartContainer" style="height:500px; max-width:700px; margin: 0 auto"></div>
var dataSource = [
    { date: new Date(2012, 3, 2, 6, 35), traffic: 3 },
    { date: new Date(2012, 3, 2, 7, 50), traffic: 8 },
    { date: new Date(2012, 3, 2, 9, 0), traffic: 7 },
    { date: new Date(2012, 3, 2, 10, 20), traffic: 5 },
    { date: new Date(2012, 3, 2, 10, 50), traffic: 5 },
    { date: new Date(2012, 3, 2, 11, 35), traffic: 6 },
    { date: new Date(2012, 3, 2, 12, 14), traffic: 7 },
    { date: new Date(2012, 3, 2, 13, 42), traffic: 8 }
