Scichart TextAnnotation out of main area

Question

I have 4 TextAnnotations put on the 4 corners of a scichart, like below:

<s:TextAnnotation x:Name="topLeftText" HorizontalAnchorPoint="Left" VerticalAnchorPoint="Top"
                                  CoordinateMode="Relative" X1="0" Y1="0"
                                  Background="Transparent" Foreground="White" BorderThickness="0" FontSize="12"/>
<s:TextAnnotation x:Name="topRightText" HorizontalAnchorPoint="Right" VerticalAnchorPoint="Top"
                                  CoordinateMode="Relative" X1="1" Y1="0"
                                  Background="Transparent" Foreground="White" BorderThickness="0" FontSize="12">
<s:TextAnnotation x:Name="bottomLeftText" HorizontalAnchorPoint="Left" VerticalAnchorPoint="Bottom"
                                  CoordinateMode="Relative" X1="0" Y1="1"
                                  Background="Transparent" Foreground="White" BorderThickness="0" FontSize="12">
<s:TextAnnotation x:Name="bottomRightText" HorizontalAnchorPoint="Right" VerticalAnchorPoint="Bottom"
                                  CoordinateMode="Relative" X1="1" Y1="1"
                                  Background="Transparent" Foreground="White" BorderThickness="0" FontSize="12"/>

But sometimes the right 2 TextAnnotations will act weird compared with normal situation (out of main area, see attached picture), can you tell me why?

TextAnnotation out of main area:

TextAnnotation normal:

I want to know the reason and how to correct it.

Answer 1

This seems to work with the latest version of SciChart WPF. Are you by chance using an old version?

If you suspect a bug, report it to the scichart forums
