Description narcís calvet 2013-11-22 05:28:22 EST

There is an extra horizontal "Ghost" line the chart if I set TColorLineTool's axis to bottom, and there will be no line if I set axis to right. This only occurs in 2D chart. An image demonstrating the issue is available at http://www.teechart.net/support/viewtopic.php?f=3&t=14525&p=63983#p63982 

Code to reproduce:

uses TeeTools, Series;

procedure TForm1.FormCreate(Sender: TObject);
var ColorLine1  : TColorLineTool;
begin
  Chart1.View3D:=False;
  Chart1.AddSeries(TFastLineSeries.Create(Self)).FillSampleValues;

  ColorLine1:=TColorLineTool.Create(Self);
  ColorLine1.Axis:=Chart1.Axes.Bottom;
  ColorLine1.Pen.Color:=clLime;
  ColorLine1.Pen.Width:=3;
  ColorLine1.Value:=Chart1[0].Count / 2;
end;

Comment 2 narcís calvet 2013-11-25 05:21:35 EST

Still not working when associating the ColorLine to the left axis: http://www.teechart.net/support/viewtopic.php?f=3&t=14525&p=64013#p64013

Code to reproduce:

uses TeeTools, Series;

procedure TForm1.FormCreate(Sender: TObject);
var ColorLine1  : TColorLineTool;
begin
  Chart1.View3D:=False;
  Chart1.AddSeries(TFastLineSeries.Create(Self)).FillSampleValues;

  ColorLine1:=TColorLineTool.Create(Self);
  ColorLine1.Axis:=Chart1.Axes.Left;
  ColorLine1.Pen.Color:=clLime;
  ColorLine1.Pen.Width:=3;
  Chart1.Draw;
  ColorLine1.Value:=ColorLine1.Axis.Minimum + (ColorLine1.Axis.Maximum - ColorLine1.Axis.Minimum) / 2;
end;
