* Defines a JavaScript OHLC stock-chart series in the SciChart's High Performance Real-time
* {@link https://www.scichart.com/javascript-chart-features | JavaScript Charts}
* @remarks
* To add an OHLC series to a {@link SciChartSurface} you need to declare both the {@link FastOhlcRenderableSeries | RenderableSeries}
* and a {@link OhlcDataSeries | OhlcDataSeries}. Simplified code sample below:
*
* ```ts
* const sciChartSurface: SciChartSurface;
* const wasmContext: TSciChart;
* // Create and fill the dataseries
* const dataSeries = new OhlcDataSeries(wasmContext);
* dataSeries.append(dateValues, openValues, highValues, lowValues, closeValues);
* // Create the renderableSeries
* const ohlcSeries = new FastOhlcRenderableSeries(wasmContext);
* ohlcSeries.dataSeries = dataSeries;
* // append to the SciChartSurface
* sciChartSurface.renderableSeries.add(ohlcSeries);
* ```
