Hi,

I have a chart with 4 axes (two X and two Y), when I try use AnnotationCreationModifier to create annotation, I get next error:

Hi there,

Thanks for reporting this! We could reproduce it on our side. It is related to multiple X axes, but AnnotationCreationModifier doesn’t provide the XAxisId property for such cases, so we will add it in next version. Fortunately, there is a simple workaround, you need to set XAxisId for used anotation types, and this can be done inside Style. Please, take a look at our Create annotations dynamically example, you can find annotation styles defined inside UserControl.Resources definition.
Just add a setter for XAxisId:

        <Style x:Key="TextAnnotationStyle" TargetType="s:TextAnnotation">
            <Setter Property="XAxisId" Value="[axis id]"/>
            ...
        </Style>

Please, let us know if the above helps!

Best regards,
Yuriy
