Some problems with BarSeries BarWidthPercent introduced in v2010.02.
procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.View3D:=false;
  Chart1.Legend.Visible:=false;
  with Chart1.AddSeries(TBarSeries) as TBarSeries do
  begin
    FillSampleValues();
    BarWidthPercent:=100;
    ColorEachPoint:=true;
  end;
end;
1. See the picture "superposed" made with the code above.
2. If you zoom, the bars become separated. See the picture "zoomed_separated". If you have a lot of bars, AutoBarSize=true seems to fix the problem, but only for moderated zooms.
3. If you set AutoBarSize=true, the problems above still happen and a new one appears: if you scroll the chart, the bars become thinner and separated. See the picture "AutoBarSize_scrolled".
In v2010.01 the problems #1 and #2 didn't happen at all, and the #3 was slightly different: with AutoBarSize=true, when you scroll the chart, the bars don't become separated but the last bar gets thinner.
