3d chart - exporting to XPS | WPF Chart Forums

Hello,

I would like to know if there is a possibility to export 3d charts to XPS format. I’ve tried using ExportToFile extension method:
sciChart.ExportToFile(filePath, ExportType.Xps, true);

While this method works well on 2d chart, it throws an exception:

InvalidCastException: Unable to cast object of type ‘SciChart.Charting3D.SciChart3DSurface’ to type ‘SciChart.Charting.Visuals.SciChartSurface’.

Stack Trace:
at SciChart.Charting.Visuals.SciChartSurfaceBase.CreateCloneOfSurfaceInMemory(Size newSize)
at SciChart.Charting.Visuals.SciChartSurfaceBase.ExportToFileInternal(String fileName, ExportType exportType, Boolean useXamlRenderSurface, Nullable`1 size)
at SciChart.Charting.Visuals.SciChartSurfaceBase.ExportToFile(String fileName, ExportType exportType, Boolean useXamlRenderSurface)
…

It suggests there is no way to export 3d charts, am I correct?

Hi Wojchiech,

Exporting a 3D Chart to XPS is not going to be possible, because the 3D Chart is drawn using DirectX (not vector primitives).

We would suggest instead to export to PnG or Bitmap and embed the result into an XPS document.

If you require further assistance, open a support ticket and we’d be glad to show you how.
