valueAxis.minorUnit Number

The interval between minor divisions. It defaults to 1/5 of the valueAxis.majorUnit. If the valueAxis.type is set to "log", the minorUnit value represents the number of divisions between two major units and defaults to the major unit minus one.

Example - set the value axis minor unit

<div id="chart"></div>
<script>
$("#chart").kendoChart({
  valueAxis: {
    minorUnit: 2
  },
  series: [
    { data: [1, 2, 3] }
  ]
});
</script>

Example - set the logarithmic value axis minor unit

<div id="chart"></div>
<script>
$("#chart").kendoChart({
  valueAxis: {
    type: "log",
    minorUnit: 2,
    minorGridLines: {
      visible: true
    }
  },
  series: [
    { data: [1, 10] }
  ]
});
</script>
