JavaScript/jQuery PolarChart - valueAxis.visualRange

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.
