Since r39379, use DownLinePen property

Hello,
I've tried it and it doesn't go well. In this example, the second tick should be blue and Red leaves.
Code: [Select]
procedure TForm1.Button1Click(Sender: TObject);
var ylist: array [1..4] of Double;
begin
  Chart1.Margins.Bottom := 20;     // Margenes
  Chart1.Margins.Left := 20;
  Chart1.Margins.Right := 20;
  Chart1.Margins.Top := 20;

  Chart1OpenHighLowCloseSeries1.TickWidth := 5;  // Ancho del tick
  Chart1OpenHighLowCloseSeries1.ListSource.YCount := 4;

  Chart1OpenHighLowCloseSeries1.LinePen.Color:=clBlue;
  Chart1OpenHighLowCloseSeries1.LinePen.Width:=3;
  Chart1OpenHighLowCloseSeries1.DownLinePen.Color:=clRed;
  Chart1OpenHighLowCloseSeries1.DownLinePen.Width:=3;

  ylist[1] := 10.9;  // O
  ylist[2] := 10.2;  // C             // O C H L
  ylist[3] := 11;    // H
  ylist[4] := 9.9;   // L
  Chart1OpenHighLowCloseSeries1.AddXY(1, 9.9, ylist);

  ylist[1] := 11;
  ylist[2] := 10.9;
  ylist[3] := 11.3;
  ylist[4] := 10.4;
  Chart1OpenHighLowCloseSeries1.AddXY(2, 10.4, ylist);

  ylist[1] := 10.5;
  ylist[2] := 10.7;
  ylist[3] := 11.2;
  ylist[4] := 10.3;
  Chart1OpenHighLowCloseSeries1.AddXY(3, 10.3, ylist);

  ylist[1] := 10.7;
  ylist[2] := 10.4;
  ylist[3] := 11.7;
  ylist[4] := 10.2;
  Chart1OpenHighLowCloseSeries1.AddXY(4, 10.2, ylist);
end;

Anyway, the ideal was that it could choose the color of the individual tick. Imagine I want that the ticks above average are blue and those who go down here to Red:

To do this you would operate the fifth parameter of the AddXY function:

Chart1OpenHighLowCloseSeries1.AddXY(4, 10.2, ylist,'',clRed);
or
Chart1OpenHighLowCloseSeries1.AddXY(4, 10.2, ylist,'',clBlue);

With this we would have total control in the color of the tick

Best regards

Spanish:
Ya lo he probado y no va bien. En este ejemplo, el segundo tick debería ser azul y sale rojo.

De todas formas, lo ideal era que se pudiera elegir el color del tick individual. Imagina que quiero que los ticks por encima de una media sean azules y los que van por abajo rojo como aquí:

Para ello tendría que funcionar el quinto parámetro de la función AddXY:

Con esto tendríamos control total en el color del tick

Un saludo

Did you modify YIndex properties? By default, y values are ordered "Low, Open, Close, High",
which does not correspond to comments in your code.

Done in r39398

Perfect!

But the order of YIndex are not correct:

If I change the order go wrong the tick:

I use Win32.

Yes, this is what I have told in previous message, Y values are incorrectly assigned in your code.
Note that YIndex is zero-based, and AddXY receives zeroth Y value and a list of the rest
as a separate arguments.
