Hi !

Some of our customers use a TSeriesRegionTool for displaying the region above the curve in a different color / gradient. If they save the file und load it back the TSeriesRegionTool is gone.
It has no assigned Series. This is the export to native data ...

Code: Select all

  object ChartTool1: TSeriesRegionTool
    Gradient.EndColor = clWhite
    Gradient.StartColor = clBlue
    Gradient.Visible = True
    Brush.BackColor = clWhite
  end

Why don´t you save the series with the tools? Is there any way to store the used series, too?

Hi Dominik,

Could you try the following simple test? This works fine for me using latest internal steema sources.

Note that, at design time, I've added two charts and an ImportChart component. Finally, I've added a line series and a series region tool to the chart1.

Code: Select all

uses TeeStore;

procedure TForm1.FormCreate(Sender: TObject);
begin
  //Chart1.View3D := False;
  with ChartTool1 do
  begin
    Gradient.EndColor := clWhite;
    Gradient.StartColor := clBlue;
    Gradient.Visible := True;
    Brush.BackColor := clWhite;
    Series := Series1;
  end;

  ImportChart1.Chart := Chart2;
  SaveChartToFile(Chart1,'C:\tmp\test.tee',true);
  ImportChart1.LoadFromFile('C:\tmp\test.tee');
end;

Hi Yeray,

I did some further tests and figure out the problem.

The series isn´t stored if you have dynamically generated Series.

Try the following:
- Add a chart to a form.
- Add a Region Tool to that chart
- Add a TFastLineSeries to the Chart and use this code:

Code: Select all

  Chart2[0].FillSampleValues(100);
  ChartTool2.Series := Chart2[0];
  SaveChartToFile(Chart2, 'c:\test.tee', True, True);

The result will this:

Code: Select all

  object ChartTool2: TSeriesRegionTool
    Brush.BackColor = clWhite
    Series = Series2
  end

As you can see ... The series is added correctly.

Now delete the series from the chart and run this code:

Code: Select all

  Chart2.AddSeries(TFastLineSeries);
  Chart2[0].FillSampleValues(100);
  ChartTool2.Series := Chart2[0];
  SaveChartToFile(Chart2, 'c:\test.tee', True, True);

You will get this:

Code: Select all

  object ChartTool2: TSeriesRegionTool
    Brush.BackColor = clWhite
  end

So what can I do to get the series stored in the Tee file (or the stream)?

Hi Dominik,

You are right. It seems that Region series link is not saved in the tee file when the series is added to the chart at runtime.

I've added it to the wish list to be fixed in future releases (TV52013106). And I'm afraid I can't think on any satisfying workaround for this by the moment.

Well well well ....

That are not really good news.
And it wont be possible to have that fix within the 8.03 release?

Hi Dominik,

I'm afraid development of v8.03 has already been closed. We are currently testing the installers and fixing any issue they may have to make the version public ASAP.
