RadzenCandlestickSeries<TItem> Class

A chart series that displays financial data as candlesticks (OHLC) in a RadzenChart. Each candlestick represents four values: Open, High, Low, and Close for a given category (typically a date). The body of the candlestick spans from Open to Close, and the wicks extend to High and Low. Bullish candles (Close > Open) use BearFill and bearish candles use BearFill.
