Creates a new RSGraphCharts.TRSGraphChartValue instance and adds it to the Items array. Call Add to create a graph chart value, or node, 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.

Add returns the new graph chart 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: RSGraphCharts

expandingSyntax

Delphi

public
  function Add: TRSGraphChartValue; overload;
 

Return Value

Type: TRSGraphChartValue

expandingExamples

The following example creates values in the collection:

Delphi

var
   Value: TRSGraphChartValue;  // 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.Width := 30;
   Value.Height := 40;
   Value.ImageIndex := 0;
   // this code adds the same point but much more quickly
   Value := MyChart.Values.Add( RSRect(10.0, 20.0, 30.0, 40.0), 'One', clRed, 0 );
 end;
