How to retrieve a QCandlestickSet item from a QChartView?

I need to be able to retrieve the QCandlestickSet items from a QChartview. I mean, not as QGraphicItems but QCandelsticksets. The reason is because, when zooming pressing the "+"/"-" key, I want the Y axis scaled properly. For that I need to know the maximum value of the QCandlestickSets is the zoomed area.

Is there any way?

Thank you very much in advance.

Sorry,

in the last sentence I wanted to write:

"For that I need to know the maximum value of the QCandlestickSets in the zoomed area."

Hello!
I think QVCandlestickModelMapper can useful for this issue, because it has methods highRow() and lowRow(). This methods, if I understand rightly, may return maximum and minimum values of candles in candle series.
