{My first attemp was partly flushed, therefore another try}

I am trying to create a chart that uses data from a query. But I simply
do not manage to get the chart accept the data I provide it with: it doe
show a chart, but the data are random - and not mine...
The code I use is:

procedure TForm1.XXX;
var i : integer;
begin
  ...
  with Chart1 do
  begin
    ...
    OpenData[COD_VALUES] := MakeLong(1, QueryWithData);
    i := 0;
    QueryWithData.First;
    while not QueryWithData do
    begin
      Value[i] := QueryWithData.FieldByName('Y_VALUE').AsInteger        
      inc(i);
      QueryWithData.Next;
    end;
    CloseData[] := 0;
    ...
  end;
..
end;

On using Delphi's watch function, it shows that the "Chart1.Value[i]"
doesn't get a value!!!

What am I doing wrong? (Or is Chart FX indeed a demo, and does not accept
real data...)

Thanks in advance,

This ought to be the number of data points in your series.

CloseData[COD_Values] := 0;

ChartFX (version 2) coming with Delphi works alright.
There is a version 3.0 demo which does everything but accept data. Check the
version numbers.

With the above modifications your routine should work

Hope that helps
