JavaScript/jQuery Chart - argumentAxis.aggregationInterval

Specifies the length of aggregation intervals in axis units. Applies only to axes of continuous and logarithmic types.

Default Value: undefined

For data aggregation, the argument axis is divided into intervals. Series points that fall within the same interval get aggregated together. The aggregationInterval property defines the length of each interval.

If the axis displays numbers, assign a number to this property. For example, an aggregationInterval of 100 produces the following intervals: 0 to 100, 100 to 200, 200 to 300, etc. If the axis displays date-time values, set this property to one of the accepted string values. Alternatively, you can set it to an object that contains one of the fields described in this section.

JavaScript
  • $(function() {
  • $("#chartContainer").dxChart({
  • // ...
  • argumentAxis: {
  • // Interval of one day
  • aggregationInterval: "day",
  • // Interval of five days
  • aggregationInterval: { days: 5 }
  • }
  • });
  • });

On a logarithmic axis, intervals are calculated based on powers. For example, if the logarithmBase is 10 and the aggregationInterval is 1, the following intervals are produced: 100 to 101, 101 to 102, 102 to 103, etc. If the aggregationInterval becomes 2, intervals become longer: 100 to 102, 102 to 104, 104 to 106, etc.
