Ohlc and Candlestick
RadChartView introduces support for stock series – both Ohlc (Open-High-Low-Close) and Candlestick. These series operate with special data points which hold information about each the following parameters: open, high, low, close. As members of the Categorical series, stock series plot their data upon a categorical (or DateTimeCategorical) axis.
Ohlc and Candlestick series are indeed two alternative ways to visualize the same data. Here is how to read the values of an Ohlc and Candlestick point:
| Ohlc | Candlestick |

Here is how to setup Ohlc series:
Initial Setup OhlcSeries
OhlcSeries ohlcSeries = new OhlcSeries();
ohlcSeries.DataPoints.Add(new OhlcDataPoint(10, 11, 7, 8, DateTime.Now));
ohlcSeries.DataPoints.Add(new OhlcDataPoint(8, 9, 5, 9, DateTime.Now.AddDays(1)));
ohlcSeries.DataPoints.Add(new OhlcDataPoint(12, 12, 9, 10, DateTime.Now.AddDays(2)));
ohlcSeries.DataPoints.Add(new OhlcDataPoint(7, 10, 6, 9, DateTime.Now.AddDays(3)));
this.radChartView1.Series.Add(ohlcSeries);
Dim ohlcSeries As New OhlcSeries()
ohlcSeries.DataPoints.Add(New OhlcDataPoint(10, 11, 7, 8, DateTime.Now))
ohlcSeries.DataPoints.Add(New OhlcDataPoint(8, 9, 5, 9, DateTime.Now.AddDays(1)))
ohlcSeries.DataPoints.Add(New OhlcDataPoint(12, 12, 9, 10, DateTime.Now.AddDays(2)))
ohlcSeries.DataPoints.Add(New OhlcDataPoint(7, 10, 6, 9, DateTime.Now.AddDays(3)))
Me.RadChartView1.Series.Add(ohlcSeries)

Here is how to setup Candlestick series:
Initial Setup CandlestickSeries
CandlestickSeries candlestickSeries = new CandlestickSeries();
candlestickSeries.DataPoints.Add(new OhlcDataPoint(10, 11, 7, 8, DateTime.Now));
candlestickSeries.DataPoints.Add(new OhlcDataPoint(8, 9, 5, 9, DateTime.Now.AddDays(1)));
candlestickSeries.DataPoints.Add(new OhlcDataPoint(12, 12, 9, 10, DateTime.Now.AddDays(2)));
candlestickSeries.DataPoints.Add(new OhlcDataPoint(7, 10, 6, 9, DateTime.Now.AddDays(3)));
this.radChartView1.Series.Add(candlestickSeries);
Dim candlestickSeries As New CandlestickSeries()
candlestickSeries.DataPoints.Add(New OhlcDataPoint(10, 11, 7, 8, DateTime.Now))
candlestickSeries.DataPoints.Add(New OhlcDataPoint(8, 9, 5, 9, DateTime.Now.AddDays(1)))
candlestickSeries.DataPoints.Add(New OhlcDataPoint(12, 12, 9, 10, DateTime.Now.AddDays(2)))
candlestickSeries.DataPoints.Add(New OhlcDataPoint(7, 10, 6, 9, DateTime.Now.AddDays(3)))
Me.RadChartView1.Series.Add(candlestickSeries)
