How can I produce a scatter chart with lines joining successive points in the order they are input, as for example in MS EXCEL'S XY (Scatter) chart type.
Thanks Nick

Hi Nick,
You can use a TLineSeries and make its pointer visible:
Code: Select all
procedure TForm1.FormCreate(Sender: TObject);
begin
Chart1.View3D:=false;
Series1.FillSampleValues();
Series1.Pointer.Visible:=true;
Series1.Pointer.Style:=psDiamond;
end;

Hi Narcis,
Will this chart in the order the data is input rather than in ascending x-axis order?
Thanks NickH

Hi NickH,
Then you may better use a TPoint3DSeries and something like this:
Code: Select all
procedure TForm1.FormCreate(Sender: TObject);
begin
Chart1.View3D:=false;
With Series1 do
begin
AddXY(8,7);
AddXY(1,4);
AddXY(2,5);
AddXY(7,3);
AddXY(6,2);
AddXY(5,7);
AddXY(9,1);
Pointer.Style:=psDiamond;
Pen.Color:=Color;
end;
end;
