Description yeray alonso 2014-04-02 06:29:05 EDT 
Having a Title in the Legend, if you also have it with fosRoundRectangle ShapeStyle, the legend title may be cut by the legend border.

Code to reproduce the issue and workaround below. The workaround consists on manually positioning the legend's text accessing the TCustomTextShape's ITextOffset property. But it would be interesting to offer some public property to change this offset and/or have some Text Align property for the legend title.

uses Series, TeCanvas;

Type
  TCustomTextShapeClass = Class(TCustomTextShape);

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  Chart1.View3D:=false;

  for i:=0 to 4 do
    with Chart1.AddSeries(TLineSeries) as TLineSeries do
    begin
      FillSampleValues(10);
      Pointer.Visible:=true;
    end;

  Chart1.Legend.ShapeStyle:=fosRoundRectangle;
  Chart1.Legend.RoundSize:=40;
  Chart1.Legend.Title.Caption:='My series';
  Chart1.Legend.Symbol.Squared:=false;
  Chart1.Legend.Symbol.Width:=50;

  //Workaround
  {Chart1.Legend.Title.AutoSize:=false;
  Chart1.Legend.Title.Height:=20;
  Chart1.Legend.Title.Width:=80;
  TCustomTextShapeClass(Chart1.Legend.Title).ITextOffset:=13;{}
end;
