Creates a new FMX.RS.BarCharts.TRSHighLowAverageChartValue instance and adds it to the Items array. Call Add to create a high/low/average bar 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 bar value.
Note that because every time you change a value an event is called, it is faster to add and initialize a value using the overloaded Add method.
Namespace: FMX.RS.BarCharts
Return Value
Type: TRSHighLowAverageChartValue
The following example creates values in the collection:
Delphi
|
var
Value: TRSHighLowAverageChartValue; // 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;
// this code adds the same point but much more quickly
Value := MyChart.Values.Add( EncodeDate(1999, 1, 30), 50, 100, 30, 'One', clRed );
end;
