JavaScript/jQuery Chart - valueAxis.visualRange

Defines the axis' displayed range. Cannot be wider than the wholeRange.

Type:

Object

Array<Number | String | Date>

Raised Events: onOptionChanged

Cannot be used in themes.

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 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 option.

The specified visual range is adjusted automatically when the argument axis is zoomed and panned. Set adjustOnZoom to false to disable this behavior.

endValue

The range's end value.

Type:

Number

Date

String

Default Value: undefined

Raised Events: onOptionChanged

length

The range's length.

Type:

Number

Object

String

Default Value: undefined

If the axis/scale displays numbers, set this option to a number:

length: 100 // a hundred axis/scale values

If the axis/scale displays date-time values, set it to an accepted string value or object that contains a field described further in this section:

length: 'day' // one day
length: { days: 2 } // two days

When using the widget as an ASP.NET MVC Control, you can specify this option with the VizTimeInterval enum which accepts the same predefined values, but they start with an upper-case letter, for example, "day" becomes Day.
