I am finding if my series has a lot (i.e. ~100) of data points and I use the "OtherSlice" property to reduce the number of slices it shrinks the entire chart. Everything else is working (i.e. data points not making the otherslice value are placed in the "other" slice).

Here is an example where I use "OtherSlice" against ~100 data points:

Here is an example where I aggregate myself, reducing down to 10 points:

Hi mSchenkel,

Could you please send us a simple example project we can run as-is to reproduce the problem here?
The following code tries to draw a chart similar to yours and it seems to be drawn as expected:

Code: Select all

uses series;

procedure TForm1.FormCreate(Sender: TObject);
var pie: TPieSeries;
    i: Integer;
begin
  pie:=Chart1.AddSeries(TPieSeries.Create(self)) as TPieSeries;

  pie.Add(413,'(not set)');
  pie.Add(266,'California');
  pie.Add(327,'England');
  pie.Add(805,'New York');

  for i:=0 to 25 do
    pie.Add(150,IntToStr(i));

  pie.OtherSlice.Value:=200;
  pie.OtherSlice.Style:=poBelowValue;
end;
