The part of pie-chart is not displayed when using negative values

[frolant]

For example:

'dataProvider'  : [
    {
      'title': 'category 1',
      'value': -20
    },
    {
      'title': 'category 2',
      'value': 10
    },
    {
      'title': 'category 3',
      'value': -30
    }
  ]

Expectation: Part of the chart with a value of 30 is displayed. Parts with negative values ​​- are hidden.

Result: All parts of the chart ​​are hidden.

The value axis scale should automatically adjust to negative values, unless explicitly disabled.
