Cannot be used in themes.

This property 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 axis's valueType. You can also set one of the array values to null to specify an open-ended range.

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

    An alternative to the two-item array.

    visualRange: {
        startValue: 50,
        endValue: 70
    }
    // Open-ended range
    visualRange: {
        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.

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

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

    visualRange: {
        length: 20
    }

To specify the minimum visual range that a user can set, use the minVisualRangeLength property.
