Here is a bit of code that does something with ChartFX.  There is not much out there in the way of examples, so this may help someone.

unit Unit1;
 interface

 uses
  SysUtils, WinTypes, WinProcs, Messages, Classes, Graphics, Controls,
  Forms, Dialogs, StdCtrls, VBXCtrl, Chart2fx, ChartFx;

 type
  TForm1 = class(TForm)
    ChartFX1: TChartFX;
    Button1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

 var
  Form1: TForm1;

 implementation

 {$R *.DFM}

const NumberOfSalesReps = 24;

procedure TForm1.FormCreate(Sender: TObject);
var
  i : integer;
begin
  randomize;
  with ChartFX1 do begin
    OpenData[COD_VALUES] := MAKELONG(1, NumberOfSalesReps);
    ThisSerie := 0; {this sets the Y-Values}
    for i := 0 to NumberOfSalesReps - 1 do Value[i] := random(100);
    CloseData[COD_VALUES] := 0;

    {this sets the X-Values}
    OpenData[COD_XVALUES] := MAKELONG(1, NumberOfSalesReps);
    for i := 0 to NumberOfSalesReps - 1 do XValue[i] := random(100);
    CloseData[COD_XVALUES] := 0;
  end;
 end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  FormCreate(Sender); {Just to watch the values change.}
end;

end.
