CAnnotationTool Custom Position

nbp · Post by **nbp** » Wed Mar 18, 2009 9:27 pm

I'm trying to set various properties of CAnnotationTool via my code.

1) What property do I use to set the Custom Position on/off and also the Left and Top values of the Custom Position?

I'm using TChart V7 and Visual C++ 9.0

Thanks.

Hi nbp,

To place your annotation in one of the predefined positions of your chart, you could use one of the following sentences:

Code: Select all

TChart1.Tools.Items(0).asAnnotation.Position = ppCenter
TChart1.Tools.Items(0).asAnnotation.Position = ppLeftBottom
TChart1.Tools.Items(0).asAnnotation.Position = ppLeftTop
TChart1.Tools.Items(0).asAnnotation.Position = ppRightBottom
TChart1.Tools.Items(0).asAnnotation.Position = ppRightTop

And to place it in a custom position, for example:

Code: Select all

  TChart1.Tools.Items(0).asAnnotation.PositionUnits = puPixels
  TChart1.Tools.Items(0).asAnnotation.Left = 200
  TChart1.Tools.Items(0).asAnnotation.Top = 300

How do I know if the Annotation position is Custom or not? Is there a boolean flag associated with CAnnotationTool? I'm using TChart v7.

In V7, I don't have access to Left and Top properties in CAnnotationTool

Hi nbp,

The boolean you are looking for:

Code: Select all

TChart1.Tools.Items(0).asAnnotation.Shape.CustomPosition = True

Are you sure that you have the latest v7 available? Here with TeeChart v7.0.1.4 I can use:

Code: Select all

TChart1.Tools.Items(0).asAnnotation.Left = 20
TChart1.Tools.Items(0).asAnnotation.Top = 50

or also:

Code: Select all

TChart1.Tools.Items(0).asAnnotation.Shape.Left = 20
TChart1.Tools.Items(0).asAnnotation.Shape.Top = 50
