Creates a new RSCharts.TRSGuideChartValue instance and adds it to the Items array. Call Add to create a guide 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 guide.

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: RSCharts

Delphi

public
  function Add: TRSGuideChartValue; overload;
 

Return Value

Type: TRSGuideChartValue

The following example creates values in the collection:

Delphi

var
   Value: TRSGuideChartValue;  // 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.X := 10.0;
   Value.Y := 20.0;
   Value.Orientation := loVertical;
   // this code adds the same point but much more quickly
   Value := MyChart.Values.Add( 10.0, 20.0, 'One', clRed, loVertical );
 end;
