I’ve implemented scrollbar like Custom view example, with Binding of XAxis VisibleRange to ViewModel.
My Problem:
If I change the value of the ViewModel the Visible Range will get changed correctly. Next step is that i click on the scrollbar and the VisibleRange will switch back to the last value.

Example:
1st: 1000-> Change to 1500-> Everything correctly-> Click on the Scrollbar-> Change back to 1000??`

<s:SciChartSurface.XAxis>
            <s:NumericAxis Name="xAxis" VisibleRange="{Binding ChartXRange,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
        </s:SciChartSurface.XAxis>

  <s:SciChartScrollbar Grid.Row="1"  Axis="{Binding ElementName=xAxis}" />
