I have a project that shows some data series and their FFTs on a scichart.

Now I need the chart to only show an FFT from a portion of the data series. The overview control’s functionality is perfect for this, but as far as I understand it only shows the parent surface’s data and cannot be bound to ViewModel itself (I’m using MVVM pattern)? So if I bind the overview control to the parent (FFT) control, then the overview shows a part of an FFT, and that’s not what I want.

Is there any way I could use the overview control for limiting the data range of the original data and then processing the data manually? Or do I have to create a custom control for this?

Hi Juho

Sorry about the long delay since answering! We actually have an example showing how you can customise the overview in the extreme.

Please see Custom Overview Example WPF and also the SciChartOverview documentation.

enter image description here

In this example we don’t use the overview, but instead the SciChartScrollbar to have a custom chart shown behind it. We bind the chart to our data-series to achieve showing all the series, rather than just one.

You could easily modify this example to show just a portion of your data, or a transformed version of your data.

Let me know if this helps!

Best regards,
