TRSCandleStickChartValues.Add(TRSChartValueType,TRSChartValueType,TRSChartValueType,TRSChartValueType,String,TCanvasColor) Method

Scroll Prev Top Next More

Creates a new RSBarCharts.TRSCandleStickChartValue instance and adds it to the Items array. The new instance is initialized with the X, Close, High, Low, Caption, and Color parameters (Open is set to previous value's Close and Average=Low+(High-Low)/2). Call Add to create a candlestickr value in the collection. The new value is placed at the end of the Items array, or, if the collection is Sorted, placed at the sorted point in the collection (based on a default value (0)).

Add returns the new candlestick value.

Namespace: RSBarCharts

Parameters

Type: TRSChartValueType

High

Type: TRSChartValueType

Low

Type: TRSChartValueType

Caption

Type: String

Color

Type: TCanvasColor

Return Value

Type: TRSCandleStickChartValue

The following example creates values in the collection:

Delphi

var
   Value: TRSCandleStickChartValue;  // note, this type should be the same that the chart uses (e.g., TRS2DChartValue, TRSArrowChartValue, etc)
begin
   Value := MyChart.Values.Add;
   Value.Caption := 'One';
   Value.Color := clRed;
   Value.XAsDateTime := EncodeDate(1999, 1, 30);
   Value.High := 100;
   Value.Low := 30;
   Value.Average := 50;
   Value.Open := 80;
   Value.Close := 85;
   // this code adds the same point but much more quickly
   Value := MyChart.Values.Add( EncodeDate(1999, 1, 30), 80, 85, 100, 30, 50, 'One', clRed );
end;
