procedure TFrmChartBase.Cursor2Change(Sender: TCursorTool; x, y: Integer;
const XValue, YValue: Double; Series: TChartSeries; ValueIndex: Integer);

Hi.
Which TeeChart version are you using ? The Trunc[XValue] part looks dangerous to me. Make sure the Trunc[XValue] integer returns valid index value (between 0 and Series.Count-1).
