Relative Annotations

Hi Fedor,

Thanks for your question.
I am sorry for the late response.

VerticalLineAnnotations can be partially drawn by setting the corresponding value for the VerticalAlignment property. Please take a look at the “VerticalAlignment Stretch and Partially Drawn Lines” section of the following documentation article for more details:
SciChart WPF Documentation – The VerticalLineAnnotation Type _ WPF Chart Documentation

However, to specify exact relative coordinates, I would recommend using LineAnnotation instead:
SciChart WPF Documentation – The LineAnnotation Type _ WPF Chart Documentation

Please also find the modified example project attached.

Kind regards,

Looks like LineAnnotation don’t have labels. But I need it.
OK, thank you. I will try with VerticalAlignment property.

P.S. But you can add vertical relative size for VerticalLineAnnotations (and horizontal for HorizontalLineAnnotations) in next versions ))))

Hi Fedor,

I discussed your inquiry with our team.
It is possible to set relative Y coordinates for Vertical Line Annotations.
To do so you have to set both VerticalAlignment property to Bottom or Top and CoordinateMode property to Relative Y.
Please see the modified project attached.

Please also note that if Annotation is aligned to Top, to place AnnotationLabel on the XAxis you should set the LabelPlacement property to Axis.

With best regards,
Lex
