Compatibility between IRenderableSeries and IRenderableSeriesViewModel

Hi there,

You cannot cast IRenderableSeriesViewModel to IRenderableSeries – they are different types (please see our Class Hierarchy, you can see what inherits what).

Instead, you need to convert RenderableSeriesViewModels to RenderableSeries. The way we do this in WPF is via the SeriesBinding MarkupExtension:

<!-- VIEW-->

<!-- Declare a SciChartSurface with SeriesBinding -->
<!-- Where xmlns:s="http://schemas.abtsoftware.co.uk/scichart -->
<s:SciChartSurface RenderableSeries="{s:SeriesBinding RenderableSeriesViewModels}">

   <!-- XAxis, YAxis omitted for brevity -->

</s:SciChartSurface>

// Viewmodel
private ObservableCollection<IRenderableSeriesViewModel> _renderSeriesViewModels;
public ObservableCollection<IRenderableSeriesViewModel> RenderableSeriesViewModels
{
   get { return _renderSeriesViewModels; }
   set
   {
      _renderSeriesViewModels = value;
         OnPropertyChanged("RenderableSeriesViewModels");
   }
}

The equivalent in C# code only is to use a converter, e.g.

List<IRenderableSeriesViewModel> rSeriesViewModels = ... // populate your view models
var sciChartSurface = new SciChartSurface();
sciChartSurface.RenderableSeries = new RenderableSeriesSourceCollection(rSeriesViewModels);

Best regards,
