xMin, xMax, yMin, yMax not recalculated to zero on .clear()

[illysky]

When dataset.clear() is called, calcMinMax is skipped when the values count is zero,
there xMin, xMax, yMin, yMax stay as they are and my Y- Axis doesn't scale to the new minimum entries value.

Get an exception when I force the calcMinMax despite value count being zero.

Workaround, I manually clear xMin, xMax, yMin, yMax just after calcMinMax in the .clear() function.

    open override func calcMinMax()
    {
        if _values.count == 0
        {
            return
        }
        
        _yMax = -Double.greatestFiniteMagnitude
        _yMin = Double.greatestFiniteMagnitude
        _xMax = -Double.greatestFiniteMagnitude
        _xMin = Double.greatestFiniteMagnitude
        
        for e in _values
        {
            calcMinMax(entry: e)
        }
    }

if continue, those max and min are just -INF or INF, which are also problematic. If you cleared them up, no data left, how does y axis scale to the "new minimum entries value" then? unless you set outside, but it has nothing to do with the data then. Why clear?

I would say if you have new data, just feed and call notifyDataSetChanged() so it will recalculate everything.
