I noticed that saving a chart to a file does not save any groups the user creates at runtime. Is there something else you have to do to save groups along with the chart?
Thanks.

Hi.

Using TeeChart and code bellow bar series stack group are saved and correctly loaded:

Code: Select all

Uses TeeStore,
    TeeEditPRO;   //  <--- Registerrs all series classes

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.FreeAllSeries(nil);
  Chart1.AddSeries(TBarSeries);
  Chart1.AddSeries(TBarSeries);
  Chart1.AddSeries(TBarSeries);

  Chart1.Series[0].FillSampleValues(5);
  Chart1.Series[1].FillSampleValues(5);
  Chart1.Series[2].FillSampleValues(5);

  With (Chart1.Series[0] as TBarSeries) do
  begin
    MultiBar := mbStacked;
    StackGroup := 0;
  end;
  With (Chart1.Series[1] as TBarSeries) do
  begin
    MultiBar := mbStacked;
    StackGroup := 0;
  end;


  With (Chart1.Series[2] as TBarSeries) do
  begin
    MultiBar := mbStacked;
    StackGroup := 1;
  end;

end;

procedure TForm1.btnSaveClick(Sender: TObject);
begin
  SaveChartToFile(Chart1,'d:\temp\result.tee',True); // <--- Include data
  Chart1.FreeAllSeries(nil);
end;

procedure TForm1.btnLoadClick(Sender: TObject);
begin
  LoadChartFromFile(TCustomChart(Chart1),'d:\temp\result.tee');
end;
