FR304 & BCB6

I work on a report including frxChartView. The chart uses LineSeries.
Because the number of series, as well as the number of points per series, depend of the user's choices, I need to add the series and the points dynamically. So, in the FR Chart Editor, there is no series; only the Chart with the default settings.

In the example I use for development, there are 3 series, each with 12 points.

After adding the series and the points, I have a piece of code allowing to check all points of all series (XLabel, YValue). So I know that the 3 series exist and are corectly populated.

The next instruction is PrepareReport. When the report appears, it shows only the gradient, the title, the axes, the label of the X axis, but nothing of the 3 series, except the 3 associated legends.

My question is: Is it possible that PrepareReport remove all series set in the BCB code?

select the chart object rclck to bring up editor
add series set type and props and fixeddata
here is some sample code

procedure Chart1OnBeforePrint(Sender: TfrxComponent);
var
fcount,indx,l2,l3:integer;
begin
l2 := Length(yv);
l3 := Length(xv);

fcount := currentyearfootercount;
if (fcount < 12) and (fcount > 0) then
begin
for indx := fcount to 11 do
begin
yv3 := yv3 +'0;';
end;
end;

with Chart1.SeriesData[0] do
begin
XSource := Copy(xv,0,l2-1) ;
YSource := Copy(yv,0,l2-1);
end;
l2 := Length(yv2);
with Chart1.SeriesData[1] do
begin
XSource := Copy(xv,0,l2-1) ;
YSource := Copy(yv2,0,l2-1);
end;
l2 := Length(yv3);
with Chart1.SeriesData[2] do
begin
XSource := Copy(xv,0,l2-1) ;
YSource := Copy(yv3,0,l2-1);
end;

end;
