  public double[] getPreferredYRange(ChartModel model)
  
  Description copied from interface: ChartRenderer
  
  Optional Y-range override for autoscaling.
  Renderers may return a {minY, maxY} array when the visible range should be based on derived data rather than the model's raw Y-values (e.g. indicators like MACD).
  
  Parameters:
  
  model - the layer model
  
  Returns:
  
  {minY, maxY} or null to use model Y-values
