React RangeSelector - scale.aggregationInterval

Specifies the length of aggregation intervals in scale units. Applies only to the scale of the continuous or logarithmic type.

Type:

Number

|

Object

|

String

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

For data aggregation, the scale 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 scale 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 scale 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.

        // ...
        scale: {
            // Interval of one day
            aggregationInterval: "day",
            // Interval of five days
            aggregationInterval: { days: 5 }

class App extends React.Component {
    render() {

                <Scale

                        days={5} />                 {/* Interval of five days */}
                </Scale>
            </RangeSelector>
        );
    }
}

export default App;

On a logarithmic scale, intervals are 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.
