Bug 264

There is a customer suggesting a change in TeeDBCrossTab.pas. Right now, when there is a point at a given XValue for one of the series but not for another series, a 0 value is being added. The customer suggests to add a null point for those "empty" values.

At TeeDBCrossTab.pas, starting line 305, where says:
                if tmpPoint=-1 then
                begin
                  tmpSeries.Add(tmpValue,tmpLabel,clTeeColor);
                  with Series.ParentChart do
                  for t:=0 to SeriesCount-1 do
                  if tmpSeries<>Series[t] then
                     if tmpSeries.Count>Series[t].Count then
                        for tt:=1 to (tmpSeries.Count-Series[t].Count) do
                        begin
                           Series[t].Add(0,tmpLabel);
                        end;
                end
                else
                begin
                  With tmpSeries.MandatoryValueList do
                  case Formula of
                    gfCount,
                    gfSum: Value[tmpPoint]:=Value[tmpPoint]+tmpValue;
                    end;
                  end;
                end;

He suggests to change it for:
                if tmpPoint=-1 then
                begin
                  tmpSeries.Add(tmpValue,tmpLabel,clTeeColor);
                  with Series.ParentChart do
                  for t:=0 to SeriesCount-1 do
                  if tmpSeries<>Series[t] then
                     if tmpSeries.Count>Series[t].Count then
                        for tt:=1 to (tmpSeries.Count-Series[t].Count) do
                        begin
                           Series[t].AddNull(TmpLabel); // Occupy it with a NULL value
                        end;
                end
                else
                begin
                  With tmpSeries.MandatoryValueList do
                  case Formula of
                    gfCount,
                    gfSum:begin
                      Value[tmpPoint]:=Value[tmpPoint]+tmpValue;
                      tmpSeries.ValueColor[tmpPoint]:=clTeeColor;//now this should be a valid value
                    end;
                  end;
                end;
And also at line 284 it should be:
                      for t:=0 to Series.Count-1 do
                          tmpSeries.AddNULL(Series.Labels[t]);
