Hiding the LinePen in a TLineSeries:

- In 3D, the polygons are drawn without border.
- In 2D, the line is drawn!!! And if you change to 3D the border is drawn.

If you make the Pointers visible, always in 2D:

- In v2014.12, the pointers are drawn. The line isn't drawn.
- In v2015.14 and up, the pointers are drawn. The line is also drawn!!!

Test example:

uses Series;
procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.View3D:=false;
  with (Chart1.AddSeries(TLineSeries) as TLineSeries) do
  begin
    FillSampleValues;
    LinePen.Visible:=false;
    //Pointer.Visible:=true;
  end;
end;

A workaround, as the customer suggests, is to set LinePen.Style:=psClear
Comment 1 david berneda 2015-05-11 12:14:25 EDT 
LinePen is forced always visible in 2D (setting Pen.Style to psClear is ok to make the pen invisible)

This is forced to prevent seeing nothing inadvertedly. 
One modification we can do is to not force pen visibility if the series Pointer is Visible.
