*Summary:* This example shows how to create candlestick charts in F#.

let's first create some data for the purpose of creating example charts:
*)

open Plotly.NET 

let candles =
    [|("2020-01-17T13:40:00", 0.68888, 0.68888, 0.68879, 0.6888);
      ("2020-01-17T13:41:00", 0.68883, 0.68884, 0.68875, 0.68877);
      ("2020-01-17T13:42:00", 0.68878, 0.68889, 0.68878, 0.68886);
      ("2020-01-17T13:43:00", 0.68886, 0.68886, 0.68876, 0.68879);
      ("2020-01-17T13:44:00", 0.68879, 0.68879, 0.68873, 0.68874);
      ("2020-01-17T13:45:00", 0.68875, 0.68877, 0.68867, 0.68868);
      ("2020-01-17T13:46:00", 0.68869, 0.68887, 0.68869, 0.68883);
      ("2020-01-17T13:47:00", 0.68883, 0.68899, 0.68883, 0.68899);
      ("2020-01-17T13:48:00", 0.68898, 0.689, 0.68885, 0.68889);
      ("2020-01-17T13:49:00", 0.68889, 0.68893, 0.68881, 0.68893);
      ("2020-01-17T13:50:00", 0.68891, 0.68896, 0.68886, 0.68891);

A candlestick chart is useful for plotting stock prices over time. A candle
is a group of high, open, close and low values over a period of time, e.g. 1 minute, 5 minute, hour, day, etc..
The x-axis is usually dateime values and y is a sequence of candle structures.

let candles1 = Chart.Candlestick candles

(*** condition: ipynb ***)
#if IPYNB
candles1
#endif // IPYNB

(***hide***)
candles1 |> GenericChart.toChartHTML
(***include-it-raw***)

(**
If you want to hide the rangeslider, use `withX_AxisRangeSlider` and hide it:
*)
let rangeslider = RangeSlider.init(Visible=false)

let candles2 = 
    Chart.Candlestick candles
    |> Chart.withX_AxisRangeSlider rangeslider

(*** condition: ipynb ***)
#if IPYNB
candles2
#endif // IPYNB

(***hide***)
candles2 |> GenericChart.toChartHTML
(***include-it-raw***)
