How can I add a "null candle" to a TCandleSeries?
I have two CandleSeries on the same chart, but dates of two series are not synchronized. For example, I can have two date sequences like

1st series: ..., 1 sep, 2 sep, 5 sep, 6 sep, 7 sep, 8 sep, 9 sep, 12 sep, ...
2nd series: ..., 1 sep, 2 sep, [no val], [no val], [no val], 8 sep, 9 sep, 12 sep, ...

so I need to introduce some invisible candle in 2nd series to keep it synchronized with 1st series on the chart.
Any idea?

Thanks
Best regards

Hi FM,

You don't need to add null values to a TCandleSeries. If you add a candle for each specific date, 2nd series won't draw candles for the days that doesn't have data. The example below shows you that, Series2 has a gap from 5-Sept to 10-Sept and is still synchronized with Series1.

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
var
  i: Integer;
begin
  Randomize;

  for i:=1 to 15 do
  begin
    Series1.AddCandle(EncodeDate( 2005, 9, i),random,random,random,random);
    if ((i < 5) or (i > 10)) then
      Series2.AddCandle(EncodeDate( 2005, 9, i),random,random,random,random);
  end;

  Series1.XValues.DateTime:=True;
end;
