WPF Controls inside the chart

Of course, it depends how / where you want to put them and what you want to do.

Ultimately SciChart is a WPF control, so a layout like this:

<Grid>
    <s:SciChartSurface/>
    <YourCustomControl Margin="50"/>
</Grid>

Will work just fine

Maybe you want to place a button inside an annotation on the chart, that can be done using CustomAnnotations API. Any XAML control can be put inside a CustomAnnotation which can then be placed at X1,X2 locations on the chart

Let me know if this helps
