вот код

procedure TFileWindow.Chart1MouseUp(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);
var i,j: integer;
begin
if adjusted then begin adjusted:=false;
for i:=ia to ib+1 do for j:=0 to Chart1.SeriesCount-1 do begin
with Chart1.Series[j] do
if (XValues.Count>0) and (Active) then ValueColor[i]:=Data.Color;
with Chart2.Series[j] do
if (XValues.Count>0) and (Active) then ValueColor[i]:=Data.Color; end;
ChartMinMax(Chart1); ChartMinMax(Chart2); end;
end;

однако возникает ошибка обращения к несуществующему элементу (ia и ib не вылезают за пределы количества точек)...Подскажите...
