Creating a Hi-Low-Open-Close Chart in Code

In This Topic

To programmatically create a HiLowOpenClose chart, use the following code:

C#	Copy Code
HighLowOpenCloseSeries ds = new HighLowOpenCloseSeries() { XValueBinding = new System.Windows.Data.Binding("NumberOfDay"), HighValueBinding = new System.Windows.Data.Binding("High"), LowValueBinding = new System.Windows.Data.Binding("Low"), OpenValueBinding = new System.Windows.Data.Binding("Open"), CloseValueBinding = new System.Windows.Data.Binding("Close"), SymbolStrokeThickness = 1, SymbolSize = new Size(5, 5) } ds.PlotElementLoaded += (s, e) => { PlotElement pe = (PlotElement)s; double open = (double)pe.DataPoint["OpenValues"]; double close = (double)pe.DataPoint["CloseValues"]; if (open > close) { pe.Fill = green; pe.Stroke = green; } else { pe.Fill = red; pe.Stroke = red; } };

Copy Code

HighLowOpenCloseSeries ds = new HighLowOpenCloseSeries()
{
XValueBinding = new System.Windows.Data.Binding("NumberOfDay"),
HighValueBinding = new System.Windows.Data.Binding("High"),
LowValueBinding = new System.Windows.Data.Binding("Low"),
OpenValueBinding = new System.Windows.Data.Binding("Open"),
CloseValueBinding = new System.Windows.Data.Binding("Close"),
SymbolStrokeThickness = 1,     SymbolSize = new Size(5, 5)
}
ds.PlotElementLoaded += (s, e) =>
{
PlotElement pe = (PlotElement)s;
double open = (double)pe.DataPoint["OpenValues"];
double close = (double)pe.DataPoint["CloseValues"];
if (open > close)
{
pe.Fill = green;
pe.Stroke = green;
}
else
{
pe.Fill = red;
pe.Stroke = red;
}
};

For example, if the values were provided by the application as collections, then you could use the code below to create the data series:

C#	Copy Code
// create data series HighLowOpenCloseSeries ds = new HighLowOpenCloseSeries(); ds.XValuesSource = dates; // dates are along x-axis ds.OpenValuesSource = open; ds.CloseValuesSource = close; ds.HighValuesSource = hi; ds.LowValuesSource = lo; // add series to chart chart.Data.Children.Add(ds); // set chart type chart.ChartType = isCandle ? ChartType.Candle : ChartType.HighLowOpenClose;

Copy Code

// create data series
HighLowOpenCloseSeries ds = new HighLowOpenCloseSeries();
ds.XValuesSource = dates; // dates are along x-axis
ds.OpenValuesSource = open;
ds.CloseValuesSource = close;
ds.HighValuesSource = hi;
ds.LowValuesSource = lo;

// add series to chart
chart.Data.Children.Add(ds);

// set chart type
chart.ChartType = isCandle
  ? ChartType.Candle
  : ChartType.HighLowOpenClose;

Another option is to use data-binding. For example, if the data is available as a collection of StockQuote objects such as:

C#	Copy Code
public class Quote { public DateTime Date { get; set; } public double Open { get; set; } public double Close { get; set; } public double High { get; set; } public double Low { get; set; } }

Then the code that creates the data series would be as follows:

C#	Copy Code
// create data series HighLowOpenCloseSeries ds = new HighLowOpenCloseSeries(); // bind all five values ds.XValueBinding = new Binding("Date"); // dates are along x-axis ds.OpenValueBinding = new Binding("Open"); ds.CloseValueBinding = new Binding("Close"); ds.HighValueBinding = new Binding("High"); ds.LowValueBinding = new Binding("Low"); // add series to chart chart.Data.Children.Add(ds); // set chart type chart.ChartType = isCandle ? ChartType.Candle : ChartType.HighLowOpenClose;

Copy Code

// create data series
HighLowOpenCloseSeries ds = new HighLowOpenCloseSeries();

// bind all five values
ds.XValueBinding = new Binding("Date"); // dates are along x-axis
ds.OpenValueBinding = new Binding("Open");
ds.CloseValueBinding = new Binding("Close");
ds.HighValueBinding = new Binding("High");
ds.LowValueBinding = new Binding("Low");

// add series to chart
chart.Data.Children.Add(ds);

// set chart type
chart.ChartType = isCandle
  ? ChartType.Candle
  : ChartType.HighLowOpenClose;
