[Interest] How to populate ChartView CandlestickSeries from JS?

[Federico Ferri]

Has anybody a solution to this?

Tried two different approaches:

https://stackoverflow.com/questions/66279947/qml-qtcharts-candlestickseries-repeater
https://stackoverflow.com/questions/66280361/qml-qtcharts-candlestickseries-append-returns-false

Both failed.
