This option accepts one of the following:

  • A two-item array

    Specifies the range's start and end. The array can contain a pair of numeric, string, or date-time values, depending on the scale's valueType. You can also set one of the array values to null to specify an open-ended range.

    value: [50, 70]
    // Open-ended range
    value: [null, 70]
  • An object with the startValue and endValue fields

    An alternative to the two-item array.

    value: {
        startValue: 50,
        endValue: 70
    }
    // Open-ended range
    value: {
        startValue: null,
        endValue: 70
    }
  • An object with the length and a startValue or endValue field

    Specifies the range using a start or end value and length.

    value: {
        startValue: 50,
        length: 20
    }
    // ===== or =====
    value: {
        endValue: 70,
        length: 20
    }
  • An object with the length field

    Sets the range of the specified length using the last scale value as the end value.
