Hi,

there's not a way to do this automatically. This feature is already added on our wish list to be considered for further releases.
With actual version there're are several ways to accomplish it :
1) Having the chart legend alignment to Right (as default), set it to custom position and then change left and top to desired position.
2) Draw the legend on the canvas manually, using the canvas techniques.
3) Use a ChartListBox component to display the legend items, you only must place it over the Chart (at desired pos), assign it to the Chart, and then change its properties (like hide Series Icon, back color, border, etc..) and finally via code do the following :
ChartListBox1.SelectedSeries:=nil;
to have no one series selected.

Yes I have tried with Right alignment and custom position but in that case if it crosses bottom axis legend is disappearing so that method is not feasible for me.
I am trying to accomplish the feature from TeeChart itself and try to avoid extra coding. So if you rectify disappearing of the legend then that is good for me

Hi,

in that case the best way I can think would be to do the following :

Code: Select all

  private
    { Private declarations }
    tmpRect:Trect;
    Buffer : TBitmap;

uses TeCanvas;

procedure TForm1.FormCreate(Sender: TObject);
begin
     Chart1.MarginBottom:=30;
     Chart1.Draw;
     Chart1.Legend.Hide;
end;

procedure TForm1.Chart1AfterDraw(Sender: TObject);
begin
  if chart1.Legend.Visible=true then
  begin
    Buffer:=TBitmap.Create;
    Buffer.Width:=Chart1.Legend.Width;
    Buffer.Height:=Chart1.Legend.Height;
    Buffer.Canvas.CopyRect(TeeRect(0,0,Chart1.Legend.Width,Chart1.Legend.Height),Chart1.Canvas.ReferenceCanvas,tmpRect);
  end;
  Chart1.Canvas.Draw(Chart1.Canvas.Bounds.Right div 2,Chart1.Canvas.Bounds.Bottom-Chart1.Legend.Height,buffer);
end;
