Configure the chart layout.

charts_view.api.applyOptions {
    layout = layoutOptions {
        backgroundColor = Color.LTGRAY.toIntColor()
        textColor = Color.BLACK.toIntColor()
    }
    localization = localizationOptions {
        locale = "ru-RU"
        priceFormatter = PriceFormatter(template = "{price:#2:#3}$")
        timeFormatter = TimeFormatter(
            locale = "ru-RU",
            dateTimeFormat = DateTimeFormat.DATE_TIME
        )
    }
}

Add any series to the chart and store a reference to it.

lateinit var histogramSeries: SeriesApi
charts_view.api.addHistogramSeries(
    onSeriesCreated = { series ->
        histogramSeries = series
    }
)

Add data to the series.

val data = listOf(
    HistogramData(Time.BusinessDay(2019, 6, 11), 40.01f),
    HistogramData(Time.BusinessDay(2019, 6, 12), 52.38f),
    HistogramData(Time.BusinessDay(2019, 6, 13), 36.30f),
    HistogramData(Time.BusinessDay(2019, 6, 14), 34.48f),
    WhitespaceData(Time.BusinessDay(2019, 6, 15)),
    WhitespaceData(Time.BusinessDay(2019, 6, 16)),
    HistogramData(Time.BusinessDay(2019, 6, 17), 41.50f),
    HistogramData(Time.BusinessDay(2019, 6, 18), 34.82f)

histogramSeries.setData(data)
