Description yeray alonso 2014-07-10 08:21:37 EDT 
StartLine and EndLine TColorLines in TColorBandTool are disabled by default.
This makes the Annotations on them not to be visible even if you set a text for them:

  TChart1.Aspect.View3D = False

  TChart1.AddSeries scLine
  TChart1.Series(0).FillSampleValues
  TChart1.Tools.Add tcColorband
  
  TChart1.Tools.Items(0).asColorband.Axis = TChart1.Axis.Bottom
  TChart1.Tools.Items(0).asColorband.StartValue = 5
  TChart1.Tools.Items(0).asColorband.EndValue = 10
  TChart1.Tools.Items(0).asColorband.StartLine.Annotation.Text = "Start"
  TChart1.Tools.Items(0).asColorband.EndLine.Annotation.Text = "End"

In VCL you can activate the ColorLines as follows:
http://bugs.teechart.net/show_bug.cgi?id=836

But in ActiveX you don't have access to the StartLine and EndLine TColorLines "Active" properties. This "Activate" property is what we should implement in ActiveX:

  TChart1.Tools.Items(0).asColorband.StartLine.Activate = True
  TChart1.Tools.Items(0).asColorband.EndLine.Activate = True

Setting a Text to the Annotations makes them visible without having to activate anything else in TeeChart ActiveX v2015.

Then, if you want to disable an Annotation or a ColorLine you can do it:

  TChart1.Tools.Items(0).asColorband.EndLine.AllowDrag = False
  TChart1.Tools.Items(0).asColorband.EndLine.Pen.Visible = False
  TChart1.Tools.Items(0).asColorband.EndLine.Annotation.Text = ""
