ChartDataSet min and max values not recalculated when calling clear()

[carlo-]

The method clear() of ChartDataSet is described as:

Removes all values from this DataSet and recalculates min and max value.

but the min and max values are never recalculated (or rather, reset).
Calling clear() does trigger calcMinMax(), but the variables _yMax, _yMin, _xMax, _xMin are never reset to their initial values because of a guard statement:

open override func calcMinMax()
{
    guard !values.isEmpty else { return }

    _yMax = -Double.greatestFiniteMagnitude
    _yMin = Double.greatestFiniteMagnitude
    _xMax = -Double.greatestFiniteMagnitude
    _xMin = Double.greatestFiniteMagnitude

    values.forEach { calcMinMax(entry: $0) }
}

The guard statement should come after the min max variables are reset (or even removed completely, since it wouldn't make any difference).
