Populating CandleChart with candles

After the empty instance of the CandleChart control has been created, you need to populate it with candles:

The CandleChart control requires the data source of its candles (the CandlesSource property) to be of type ICandlesSource, which is IList<ICandle> with the readonly TimeFrame property. Therefore, you have to add to your project a new class Candle that implements the ICandle interface:

    public class Candle : FancyCandles.ICandle
    {
        public DateTime t { get; set; }
        public double O { get; set; }
        public double H { get; set; }
        public double L { get; set; }
        public double C { get; set; }
        public double V { get; set; }

        public Candle(DateTime t, double O, double H, double L, double C, double V)
        {
            this.t = t;
            this.O = O;
            this.H = H;
            this.L = L;
            this.C = C;
            this.V = V;
        }
    }

And a new class CandlesSource that implements the ICandlesSource interface:

    public class CandlesSource :
            System.Collections.ObjectModel.ObservableCollection<ICandle>, 
            FancyCandles.ICandlesSource
    {
        public CandlesSource(FancyCandles.TimeFrame timeFrame)
        {
            this.timeFrame = timeFrame;
        }

        private readonly FancyCandles.TimeFrame timeFrame;
        public FancyCandles.TimeFrame TimeFrame { get { return timeFrame; } }
    }

In MainWindow.xaml.cs of your project, in the constructor of the MainWindow class:

Create an instance of CandlesSource, which will be used as the data source for the CandleChart control.

    // Let's take the 5-minute timeframe for this example: 
    FancyCandles.TimeFrame timeFrame = FancyCandles.TimeFrame.M5;
    CandlesSource candles = new CandlesSource(timeFrame);

Populate this collection with some data. In this example, we will generate a meaningless set of Candle instances:

    DateTime t0 = new DateTime(2019, 6, 11, 23, 40, 0);
    for (int i = 0; i < 500; i++)
    {
        double p0 = Math.Round(Math.Sin(0.3*i) + 0.1*i, 3);
        double p1 = Math.Round(Math.Sin(0.3*i + 1) + 0.1*i, 3);
        candles.Add(new Candle(t0.AddMinutes(i * timeFrame.ToMinutes()),
                    100 + p0, 101 + p0, 99 + p0, 100 + p1, i));
    }

Set the DataContext property to this collection of candles:
```
    DataContext = candles;
```

As a result, the constructor of your MainWindow class may looks like this:

    public MainWindow()
    {
        InitializeComponent();

        /// ... some code

        // Let's take the 5-minute timeframe for this example: 
        FancyCandles.TimeFrame timeFrame = FancyCandles.TimeFrame.M5;
        CandlesSource candles = new CandlesSource(timeFrame);

        DateTime t0 = new DateTime(2019, 6, 11, 23, 40, 0);
        for (int i = 0; i < 250; i++)
        {
            double p0 = Math.Round(Math.Sin(0.3*i) + 0.1*i, 3);
            double p1 = Math.Round(Math.Sin(0.3*i + 1) + 0.1*i, 3);
            candles.Add(new Candle(t0.AddMinutes(i * timeFrame.ToMinutes()),
                        100 + p0, 101 + p0, 99 + p0, 100 + p1, i));
        }

        DataContext = candles;
    }

In MainWindow.xaml of your project, set the CandlesSource attribute for the CandleChart element:

    <fc:CandleChart CandlesSource="{Binding Path=.}"  xmlns:fc="clr-namespace:FancyCandles;assembly=FancyCandles"/>

Finally, a set of candles should appear in your CandleChart control.
