In our project we had ScrollViewer on the LegendModifier:

<s:LegendModifier ShowLegend="True" ScrollViewer.VerticalScrollBarVisibility="Auto" x:Name="legendModifier" Orientation="Vertical" Margin="10" LegendItemTemplate="{StaticResource SciChartLegendItemTemplate}" >

It used to work with SciChart version 4.1.1.8645, but after the update to 4.2.0.9172, the scroll bar is no longer shown, which is a big problem!
Tried also with the latest version 4.2.1.9358, still not working.
I also have get this in the output:
System.Windows.Data Warning: 40 : BindingExpression path error: ‘ScrollViewer’ property not found on ‘object’ ”LegendPlaceholder’ (Name=”)’. BindingExpression:Path=ScrollViewer.HorizontalScrollBarVisibility; DataItem=’LegendPlaceholder’ (Name=”); target element is ‘SciChartLegend’ (Name=”); target property is ‘HorizontalScrollBarVisibility’ (type ‘ScrollBarVisibility’)

Hello,

This bug should be fixed in v4.2.2.9490 or greater of SciChart WPF.

Please get the nightly build from our NuGet feed and let us know the results.

Best regards,
Andrew
